When you dive into the world of ancient burial sites, the phrase top 10 unexpected instantly conjures images of hidden chambers, bizarre artifacts, and mysteries that make even seasoned archaeologists sit up straight. From forgotten scribes tucked away behind walls to toxic pools of mercury sealed for millennia, the following list showcases the most jaw‑dropping tomb finds that have forced scholars to rethink everything they thought they knew about past cultures.

Why These Top 10 Unexpected Tomb Finds Matter

Each of these discoveries not only adds a new piece to the puzzle of human history, but they also highlight how a single unexpected object can overturn long‑standing theories, reveal forgotten traditions, and sometimes even rewrite entire chapters of our collective past.

10 Secret Scribe Room

Luxor’s sprawling necropolis is already famous for its grand tombs, but a 2017 routine cleaning unearthed a surprise that still has scholars buzzing. While sweeping the forecourt of the Userhat tomb—a well‑documented royal scribe’s burial—researchers noticed a subtle fissure in the eastern wall. Curiosity got the better of them, and they pried the gap open, only to reveal a second, previously unknown funerary chamber dating from roughly 1292 to 1069 BC. Hieroglyphic inscriptions identified the hidden occupant as Khonsu, another royal scribe, whose name and titles matched those of high‑ranking officials of the era.

The newly exposed chamber is a visual feast: vivid murals depict Khonsu alongside his spouse, a pantheon of deities, and a striking scene of four baboons worshipping the sun god Ra‑Atum. Egyptians believed baboons could act as divine scribes, guiding the hand of the writer, so the presence of these primates suggests a spiritual link between Khonsu’s craft and the celestial realm. This concealed scribe’s tomb hints that Luxor may still be harboring undiscovered burial rooms, waiting for a lucky team to stumble upon them.

9 The Hermitage Finds

In the remote Irish landscape, the Hermitage burial site delivered two shocking revelations in 2001. While examining a grave that dated back roughly 9,500 years, researchers were puzzled to find no skeletal remains. Instead, the burial contained a layer of ash and charcoal, indicating a cremation—a rarity for hunter‑gatherer societies of that epoch, who typically practiced in‑situ interments. Adding to the intrigue, a polished shale axe lay among the cremated remnants.

This axe is a technological marvel, showcasing a level of craftsmanship that wouldn’t become common until three millennia later. Microscopic analysis revealed that the blade had been deliberately blunted, suggesting it was fashioned solely for ceremonial purposes. Scholars speculate that the weapon symbolized a ritualized offering, perhaps representing the deceased’s status or a symbolic “death” of the weapon itself, a practice never before documented in European prehistory.

8 Liquid Mercury

Deep beneath the famed Pyramid of the Plumed Serpent at Teotihuacan, a tunnel that had consumed archaeologists for six years finally revealed its most astonishing secret in 2015: a sealed chamber brimming with liquid mercury. The ancient metropolis, which once housed up to 200,000 inhabitants, left behind a labyrinth of tunnels that were believed to protect royal burials. When the team finally breached the final doorway, they uncovered a pool of shimmering, toxic metal that had been undisturbed for nearly 1,800 years.

Mercury was an exceptionally rare and difficult‑to‑obtain element in the ancient Americas, often associated with alchemy, the underworld, and divine protection. Its presence in a royal context suggests the buried individual—or perhaps a sacred space adjacent to the tomb—was accorded extraordinary reverence. The find fuels ongoing debates about whether Teotihuacan possessed a monarchical system at all, since the culture left no written records, and the mercury could hint at a hidden elite class or a ritualistic safeguard for the afterlife.

7 An Archetype’s Tomb

The Moche civilization of Peru, known for its vivid ceramics and dramatic tombs, surprised scholars in 2009 when a double‑chambered crypt at San Jose de Moro yielded a male burial—an unexpected twist in a site previously dominated by elite priestess interments. Dating to around AD 850, the tomb contained a gilded copper coffin, richly adorned with gold, clearly marking the occupant as a high‑ranking male figure.

Inside the tomb, clay bowls lined the walls, each holding a ceramic vessel that appears to have been heated and then lowered into the liquid‑filled bowls, creating a dramatic, smoky atmosphere during the funeral rites. A staff topped with bells lay beside the body, echoing the iconography of the Moche archetype known as Aia Paec, or “Wrinkle Face,” a figure frequently depicted wielding a similar instrument in mural art. Because Aia Paec was a living role rather than a mythic deity, archaeologists believe the interred individual was likely the historical embodiment of this archetype, granting him both ceremonial and societal prominence.

6 Missing Elements

The Valley of the Kings, the final resting place of Egypt’s New Kingdom pharaohs, yielded a baffling puzzle between 2007 and 2011. While excavating the western sector—a region that had not seen the same level of attention as Tutankhamun’s tomb—archaeologists uncovered four distinct caches arranged at the corners of an imagined square. Such foundation deposits are typical offerings placed to sanctify a new construction, often accompanied by a fifth central deposit that marks the exact location of the tomb.

Each corner cache contained a ritual item: a cow’s head, a blue ceramic vase, assorted pottery, and flint tools. Yet, despite exhaustive searching, the expected central deposit—and the tomb it would signify—remained elusive. The absence of a tomb could suggest the burial was never completed, perhaps abandoned during the religious upheaval of Amenhotep IV’s move to Amarna, or that the tomb is concealed so expertly that modern methods have yet to locate it.

5 Vault Of Ships

South Abydos, a lesser‑known necropolis in Upper Egypt, astonished researchers in 2016 when a subterranean chamber beneath the dunes revealed a maritime wonderland. The vaulted burial room, rectangular in shape, is entirely lined with more than 120 carved stone ships, each rendered in exquisite detail. Traces of additional vessels once adorning the ceiling suggest the original design may have featured an even more extensive fleet.

Among the carvings, a few original wooden planks have survived, believed to belong to a funerary boat intended for the pharaoh Senwosret III (circa 1850 BC). The sheer number of vessels, juxtaposed against Egypt’s arid desert backdrop, raises compelling questions about why this king chose a nautical tableau for his afterlife—perhaps to ensure safe passage across the celestial Nile or to symbolize his dominion over both land and water.

4 Dental Fashion

In 2009, a construction crew near a Dorset road uncovered a mass Viking burial containing over fifty warriors, their skeletal remains arranged in dismembered piles. While the violent nature of the massacre was evident, the most striking feature lay not in the weapons but in the warriors’ teeth. Each front tooth bore a series of precise, horizontal incisions—essentially dental tattoos—crafted with a level of skill that could not have been self‑administered.

Archaeologists hypothesize that these men visited a specialized craftsman to have their teeth filed, likely as a status symbol or a fearsome display meant to intimidate opponents. The practice, however, failed to deter the local Britons who slaughtered the raiders. The enigmatic dental modifications offer a rare glimpse into personal adornment customs among Viking societies, suggesting a complex interplay of identity, bravado, and perhaps even ritualized rites of passage.

3 The Backward Saint

Little Carlton, Lincolnshire, yielded an unusually positioned burial in 2011 after a silver Anglo‑Saxon stylus and a handful of glass fragments hinted at a high‑status site—possibly a monastic settlement or elite island community surrounded by water a millennium and a half ago. The most perplexing find was the corpse itself: a man laid face‑down in a cramped pit barely wider than his shoulders, with only 25 cm (10 in) separating his arms.

Despite the cramped space, the body had been carefully tended to after decomposition began. The knees were rotated a full 180 degrees, and the remains were meticulously reassembled, indicating a deliberate, reverent effort. Such treatment aligns with legends of saints or royalty whose bodies were moved post‑mortem to new burial sites, suggesting the individual may have been an Anglo‑Saxon noble or even a saint whose remains were relocated long after death.

2 The Jester God

Deep beneath a modest Mayan house in the K’o site of Guatemala, a 2008 excavation uncovered a concealed storage chamber that housed a man in his fifties surrounded by an array of pottery. Among the artifacts, a striking incense burner featured a figure wearing a tassel‑like headdress—later identified as the “jester god,” a deity associated with royalty and courtly entertainment.

Scholars recognized the jester god’s iconography, which first appears in Maya art around 100 BC. However, radiocarbon dating of the surrounding pottery and skeletal remains placed the burial at roughly 350 BC, pushing the earliest known depiction of this deity—and by extension, the earliest known Maya ruler—back by nearly two centuries.

This revelation forces a reassessment of the timeline for Maya sociopolitical development, suggesting that complex statecraft and royal symbolism emerged far earlier than previously believed, reshaping our understanding of early Mesoamerican civilization.

1 Clues To Greek Origins

In 2015, a team denied permission to excavate near the famed Palace of Nestor in the Greek Peloponnese settled for a nearby grove, where they unexpectedly uncovered the most intact Mycenaean tomb discovered in Greece since the legendary find at Troy. A vertical shaft led to a burial chamber containing a single male skeleton surrounded by a staggering 1,400 artifacts, ranging from precious metals and ivory to ornate weaponry and stone seals.

The tomb’s contents were astonishingly diverse: items traditionally associated with female burials—such as a mirror, combs, and delicate beads—sat alongside heavy weaponry and armor. Moreover, the tomb diverged from typical Mycenaean practices, which usually involve multiple interments; this was a solitary, unlooted grave dating to the murky 1500 BC period.

The eclectic assortment of artifacts, sourced from distant regions like Crete, the Baltic, the Middle East, and possibly Egypt, paints a picture of a highly cosmopolitan society. This treasure trove offers scholars a rare, undisturbed glimpse into the cultural exchanges that may have seeded the emergence of classical Greek civilization, potentially identifying the very community that laid the foundations for Western culture.

These ten astonishing tomb discoveries underscore how the most unexpected finds can upend entrenched narratives, spotlight forgotten peoples, and illuminate the rich tapestry of human history.

When it comes to memorializing the departed, most people opt for a modest headstone that lists a name, birth and death dates, and perhaps a short epitaph. But for the truly adventurous—or the downright eccentric—there are far more spectacular ways to secure a final resting place. In this roundup we spotlight 10 unusual tombs that turn the ordinary act of burial into something unforgettable, ranging from haunted glass‑encased statues to a senator who demanded to be interred inside a solid rock.

From the mist‑shrouded ridges of the Caucasus to the sun‑baked deserts of Sudan, each of these tombs tells a story that is as strange as it is fascinating. Grab your flashlight, hold onto your curiosity, and let’s explore the most bizarre burial sites on the planet.

10 Unusual Tombs Overview

10 Inez Clarke Monument

The Inez Clarke Monument stands out in Chicago’s Graceland Cemetery as a hauntingly beautiful yet puzzling tribute. A delicate statue of a young girl clutching a parasol rests atop a pedestal, all enclosed within a glass case that gives the whole scene an eerie, museum‑like quality. Legends claim the little girl comes alive during thunderstorms, wandering the cemetery grounds as if she were still playing in the rain.

Both security personnel and bus‑tour guides have swore they saw the statue disappear from its spot at night, only to find it back in place by sunrise. Adding to the mystery is the question of who actually lies beneath the monument. While the plaque reads “Inez Clarke 1873–1880,” some experts, including Chicago cemetery authority Helen Sclair, argue that a boy named Amos Briggs may be the true occupant.

9 Russia’s City of the Dead

Hidden among the jagged ridges that split the Caucasus mountains lies the eerie village of Dargavs, commonly dubbed Russia’s City of the Dead. The settlement consists of a cluster of peaked roofs and single‑window brick houses perched on a picturesque clifftop, each structure serving as an above‑ground crypt for the dead. Archaeologists estimate that roughly 10,000 bodies rest within these stone‑bound homes.

Three main theories vie for supremacy about the city’s origin. One suggests a plague forced infected residents to quarantine themselves in the one‑window houses, awaiting death. Another attributes the crypts to the 13th‑century Mongol‑Tatar invasions, when locals built compact tombhouses to conserve space. A third theory links the site to migrating Sarmatians who, following Indo‑Iranian customs, buried their dead above ground. Whatever the truth, the City of the Dead remains a haunting testament to unconventional burial practices.

8 The Russian Countess Who Wanted Company in Her Tomb

Elisabeth Demidoff, scion of a wealthy Russian industrial family, married Count Nikolai Nikitich Demidoff, only for the union to dissolve amid scandal. After separating, Elisabeth relocated to Paris, where she died in 1818 at the age of 40. Her will, however, contained a chilling clause: she bequeathed a fortune to anyone who would spend a full year and a day inside her tomb, perched beside her coffin in the famed Père Lachaise cemetery.

Over the ensuing decades, countless hopefuls attempted the macabre challenge, hoping to claim the promised riches. Yet no one ever completed the grueling vigil, and the stipulation lingered well into the early 20th century. The tale of the Russian countess adds a darkly romantic twist to the cemetery’s storied history.

7 The Tomb of Florence Irene Ford

Florence Irene Ford succumbed to yellow fever in 1871 at the tender age of ten, a child who had always feared the rumble of storms. In an effort to soothe her lingering anxieties, her mother commissioned a small glass panel to be set at the head of her daughter’s coffin, allowing a glimpse of the world even after death.

Determined to protect her child from the elements, the grieving mother also ordered a narrow stairway to descend nearly two meters (about six feet) to the burial vault. At the top of this descent, a sturdy metal trapdoor could be shut during thunderstorms, shielding the grave from wind and rain while the mother read or sang to her beloved daughter.

Florence’s final resting place can be found in Natchez City Cemetery, located at 19‑27 Cemetery Road in Natchez, Adams County, Mississippi. The cemetery itself houses several other notable monuments, each with its own unique story.

6 The Tomb of Mary Ellis

In the 1790s, Mary Ellis traveled to New Brunswick to stay with her younger sister Margaret. While there, she fell deeply in love with a sea captain rumored to be a Revolutionary War officer. The couple made plans for a shared future, but duty called the captain away across the Raritan River, promising to return and even gifting Mary his trusted horse.

Mary waited faithfully at the riverbank, riding the horse to greet the captain each day, but he never came back. Undeterred, she purchased farmland along the river and continued her vigil. By 1828, after years of waiting, Mary passed away, and her family laid her to rest near the Raritan.

During the 1960s, developers cleared the surrounding woods to build a store, leaving Mary’s headstone stranded in the middle of what became a parking lot. Despite various construction projects over the years, her solitary gravestone has remained untouched, turning the site into a poignant reminder of unwavering devotion.

5 The Tomb of Cyrus the Great

Pasargadae, the ancient capital of the Achaemenid Empire, was founded by Cyrus the Great, who ruled Persia from 559–530 BC. The sprawling complex, roughly two kilometers by three kilometers, featured monumental architecture set within a grand park‑like setting. According to Roman geographer Strabo, the palace was built on the site where Cyrus triumphed over the Median king Astyages in 550 BC.

Constructed around 530 BC, Cyrus’s tomb rises about 13 meters (42.5 feet) high and 11 meters (36 feet) wide. The structure comprises a lower base and an upper chamber, the latter housing a square burial room and an attic. A mysterious rayed disk, about 50 centimeters (20 inches) in diameter, crowns the entrance, its symbolism still debated. When Cyrus was interred, the tomb contained a gold sarcophagus, his weapons, jewelry, and cloak. Though time has eroded much of its original grandeur, the monument remains an iconic example of unconventional royal burial architecture.

4 The Okunoin Cemetery

The Shingon sect of Buddhism, based on Japan’s Mount Kōya, treats the sprawling Okunoin Cemetery not merely as a resting place but as a liminal realm for wandering spirits. Unlike conventional cemeteries, Okunoin is viewed as a waiting area where the body and spirit remain intertwined. A ceremonial bridge marks the threshold between the living world and this spiritual domain, while towering cedars line the path, creating an otherworldly corridor.

Encompassing a 1,200‑year‑old forest, Okunoin boasts the largest cemetery in Japan, housing roughly 200,000 graves. Traditional Japanese markers—headstones accompanied by wooden sticks bearing names and spaces for ashes, flowers, incense, and family seals—dot the landscape. Central to the site is the mausoleum of Kōbō Daishi (posthumously known as Kūkai), the founder of Shingon Buddhism. Among the many curiosities, the Miroku Stone stands out: a massive slab that allegedly judges a visitor’s sins, feeling heavier for the wicked and lighter for the virtuous.

3 Love Struck Even in Death

The iconic Père Lachaise cemetery in Paris, established by Napoleon in 1804 and spanning over 40 hectares (98 acres), serves as the final resting place for countless luminaries. Among its many notable graves lies the tomb of Fernand Arbelot, who died in 1942. In his will, Arbelot stipulated that a monument be erected depicting him gazing at his wife, with his hand supporting a disembodied head that stares back at the viewer.

The chilling epitaph reads, “They were amazed at the beautiful journey which led them to the end of life.” Legend has it that Arbelot hastened the creation of this macabre sculpture by murdering his wife before taking his own life. Belgian sculptor Adolphe Wansart crafted the haunting monument in 1946, cementing Arbelot’s place among the cemetery’s most eerie stories.

2 The Nubian Pyramids of Sudan

Stretching along the Nile’s banks in eastern Sudan, the Nubian pyramids form a desert‑spanning necropolis that served as the burial grounds for the royalty of the ancient Kush Kingdom for nearly a millennium. These pyramids, built between 2,700 and 2,300 years ago, blend artistic influences from Pharaonic Egypt, Greece, and Rome.

Distinct from their Egyptian counterparts, Nubian pyramids are constructed from sandstone and granite, featuring steeply sloping sides, chapels, and richly decorated burial chambers. Inside, hieroglyphic and Meroitic inscriptions celebrate the lives of the kings and queens they house, offering a vivid glimpse into the culture of Meroe, the thriving capital of the Kushite empire that once rivaled Egypt.

1 William Jeffreys Got Buried in a Rock

In 1844, 28‑year‑old William Jeffreys secured a seat in the North Carolina Senate. A year later, a severe fever struck, bringing on vivid hallucinations and an intense dread of being buried in the earth, fearing that worms would consume his remains. Determined to avoid this fate, Jeffreys insisted on being interred inside a solid rock.

Initially dismissed as a youthful whim, his condition worsened, prompting his father to honor his son’s wishes. A stone mason spent over a year carving a suitable cavity, while a marble slab bearing an inscription was commissioned. Unfortunately, the slab shattered during transport, delaying the completion of the tomb by another year. Ultimately, Jeffreys’ unique resting place stands as a testament to his extraordinary fear and the lengths his family went to fulfill his final request.

To “hermetically seal” something (after the alchemist Hermes Trismegistus) is to seal it in such a way, usually by magic, that it can never be opened. The following ten mysteries — a mixture of boxes, tombs and scrolls, as well as one letter — aren’t hermetically sealed necessarily, but some of them might as well be. In any case, none of them have ever been opened.*

10. Queen Elizabeth II’s letter

In November 1986, Queen Elizabeth II wrote an open letter to the people of Sydney, Australia. But the letter arrived sealed with a stipulation not to open it for another hundred years. So until 2085, on a day of the Lord Mayor of Sydney’s choosing, the contents of the letter will remain a mystery — kept in a vault in a restricted area in Sydney’s Queen Victoria Building. She didn’t even tell her own staff what it said.

Could it be new, Sydney-specific revelations of royal pedophilia? Could it be a decree from beyond the grave cutting Australia loose from the Commonwealth? Or maybe it cedes the throne to its rightful heirs, descendants of the Australian farmer Mike Hastings? 

Boringly, it’s assumed to have something to do with keeping the building in which it’s now housed, named after her great, great grandmother, from being demolished. It already survived this fate once, in 1959, when developers had plans for a parking lot. Then, in 1984, a Malaysian company signed a 99-year lease on the building. 

9. Bohuslav Jirus’s boxes

In 1901, the Croatian botanist, pharmacologist, philanthropist, and world traveler Bohuslav Jiruš left most of his worldly possessions to the National Museum. But the secretive professor (of whom there are no known photos) had a sense of humor; he left his estate in two wooden crates and said they mustn’t be opened for 200 years. In 2022, with 79 years still to go, museum staff realized they could use computer tomography (CT) to view the contents without having to actually open them and therefore without, technically, defying their benefactor’s wishes. 

Hoping to satisfy their curiosity within their lifetimes, they put the dilemma to a vote — asking 3,000 members of the public what they thought. To their disappointment, 53 percent voted against a CT scan. So the guesswork resumed. 

Given the weight of the crates, it’s thought they may contain objects made from copper — perhaps some kind of apparatus? Others believe the crates may house some botanical or pharmacological discovery — a medicinal plant or dangerous bacteria. At the very least, it’s assumed there’ll be a photo of the man in there somewhere and we’ll finally know what he looked like.

8. Alexander the Great’s tomb

OK, so this one has been opened — and plundered — again and again, by such luminaries as Cleopatra (to finance her war against Augustus), Caligula (to steal his breastplate), and Caracalla (to steal his tunic, ring, and belt). But nature, not humans, have since sealed it tight — and it hasn’t been opened since antiquity.

The 365 BCE tsunami that flooded Alexandria is thought to have cut off access to the tomb. In fact, along with a lot of the ancient city on which the modern city is built, it’s thought to have sunk to the seabed. But there are various other theories. It may be, as believed by Ambroise Schilizzi in 1850, in Alexandria’s Nabi Daniel Mosque — but permission to dig has never been granted. It may not even be in Alexandria at all. One theory suggests a tomb in Vergina, Greece, commonly believed to be that of Philip II of Macedon, is actually Alexander the Great’s. Another suggests it’s in Venice, within the tomb of Saint Mark beneath his Basilica. Yet another theory says it’s in the Siwa Oasis in western Egypt.

Back in Alexandria, though, Greek archaeologist Calliope Limneos-Papakosta has been searching for decades — most recently pumping out water to facilitate her digs. To date, she and her team have uncovered the city’s first roads and what they believe was the ancient royal quarter. This, she said in 2023, is where the conqueror is thought to be entombed.

7. The En-Gedi scroll

Discovered over 50 years ago in a damaged Holy Ark near the Dead Sea, the two-millennia-old En-Gedi scroll had been burned and crushed to an unopenable lump of charcoal. Opening it was out of the question; even handling the scroll risks crumbling it to dust. Archaeologists had no choice but to shelve the ancient document and forget about reading its contents.

Until recently. In 2015, computer scientist Brent Seales used his groundbreaking imaging software to “virtually unwrap” the scroll. First, he scanned it with X-rays using a micro-CT machine. Then he mapped it onto a 3D computer model of the scroll — which, given its irregular shape, was harder than it sounds. Finally, he digitally unraveled the shape to a flat page.

Although fragmentary because of the damage, resulting in just 35 lines of readable text, the scroll contained chapters of Leviticus (one of the first five books of the Torah). Written in the original Hebrew, it allows researchers to hone their understanding of the text’s early history. In fact, it’s the earliest copy of any Pentateuchal book ever found in a Holy Ark.

6. Mystery safe

When New York farmer Kirk Mathes returned to his fields from a trip out of town, he was mystified to find a 600-pound metal safe. There was no indication of who left it, or what was in it. But there was a note: “If you can open this, you can have what’s inside.”

When the press got wind of the story, Mathes farm in Barre, Orleans County, became a media circus. Apparently in an effort to play down the safe, he told reporters it was probably left by local “crazy kids … real jokers”. But crowds still descended on his farm, with some taking a sledgehammer to the safe, damaging the hinges and knocking off the handle and dial.

After calling police and hiding it away, Mathes said he plans to leave it unopened. Although bothered by the intensity of interest, he felt the mystery was fun enough to keep alive. “If you open it,” he said, “the show is over.” Now, there are plans to house the safe in a local history museum. “It could be holding millions of dollars. It could have confetti in there,” said Cindy Vanlieshout of the Barre Betterment Committee, “You have no idea, so just dream.”

5. Cleopatra’s tomb

According to archaeologist Kathleen Martinez, who has been searching for Cleopatra’s tomb for well over three decades, “Cleopatra outsmarted everyone.” She evaded the smug Roman emperor Augustus by killing herself then even denied the Empire her corpse by having it spirited away, along with Mark Antony’s, to a location that remains secret to this day. The most likely site appears to be Taposiris Magna, a temple outside Alexandria in Egypt. But it’s been many years since Martinez and her team unearthed “exciting artifacts” linked to the Queen there, including coins and Isis figurines. 

More recently, though, in 2022, they found a spectacular tunnel 13 meters undergound, two meters tall and 1,305 meters long, hewn through the sandstone bedrock. Its design, a “geometric miracle” experts say, resembles that of the Tunnel of Eupalinos on Samos, constructed in the 6th century BCE. The tunnel is a promising lead, but like the previously discovered network of tunnels connecting Lake Mariout to the Mediterranean, it’s partly submerged under water thanks to earthquakes between 320 and 1303 CE. 

If discovered, the tomb of Cleopatra will be the most important archaeological find of the 21st century. Martinez already knows what her first words will be if she is the one to uncover it: “The world has never forgotten you, Queen Cleopatra.”

4. The Herculaneum Papyri

The Herculaneum Papyri, unearthed in the other Pompeii, Herculaneum, in the late 1700s, number roughly 1,100 in total. Found in a luxurious villa belonging to Julius Caesar’s father-in-law, they constitute a tantalizing “invisible library” full of unprecedented glimpses of the classical world. In fact, the Herculaneum Papyri represent the only classical Greco-Roman library to survive intact to this day. The only trouble is, they were carbonized into black, unopenable lumps of charcoal by the eruption of Mount Vesuvius.

For centuries, researchers have attempted to get at their contents — often destroying the scrolls in the process. (Many were destroyed, either thrown into the sea or burned as coal, before their discoverers even realized what they were.) Their first archivist Camillo Paderni cut some in half, copied visible text, then scraped away each layer in turn. A couple of years later, Vatican conservator Antonio Piaggio glued the super-thin, super-tough intestinal membrane of a calf to the surface of a scroll then used weights and strings to delicately prise off each layer for artists to copy the contents. But the method was far from perfect, with many layers coming away stuck together and torn. Since then, the scrolls have been hidden away in secret vaults to protect their contents until such time as we can, somehow, open them properly. 

Now, if the “virtual unwrapping” of the En-Gedi scroll is anything to go by, it looks like that time has arrived. The same computer scientist has compiled up to 12,000 cross-sections of the papyri he’s been allowed to examine, and is now depending on artificial intelligence to sort the jumble of letters by density. Unlike the En-Gedi scroll, the Herculaneum Papyri’s authors didn’t use metal in the ink. If successful, the scrolls usher in a new “renaissance of classical antiquity,” potentially changing the canon. But archivists are understandably cautious. Even just handling the papyri can turn them to dust. So far, Seales has only imaged two but still has to wait for AI to improve.

3. Joanna Southcott’s box

Self-proclaimed Woman of the Apocalypse Joanna Southcott sold “Seals of the Lord” to simpletons, guaranteeing each buyer one of 144,000 places in Heaven. She even appears to have believed it herself, persuaded by visions that she had a sacred mission. Namely, despite being a 64-year-old virgin, she was, she claimed, to give birth to a messiah in London — the Shiloh prophesied in Genesis. To be fair, she did look pregnant enough not only to persuade herself but also to attract followers (the Community of the Holy Ghost, later renamed the Panacea Society), who built an ornate gold cradle for the baby. In the end, however, Southcott’s abdominal swelling turned out to be a condition that killed her and, eventually, reluctantly, her followers buried her corpse.

But she left plenty more prophecies in a large wooden box, bound as “instructed by the Spirit” in Seven Seals. So at least they had that to look forward to. The trouble was Southcott said it could only be opened at a time of national crisis, and only in the presence of all 24 Church of England bishops. The first part was easy. Even in the 1920s, a century after her death, Southcott’s devotees knew they were living in the end times and that her box would “guide the English nation” to safety. The bishops, however, were not so convinced — even by the Panacea Society’s ad campaign on the sides of London buses, urgently warning the public that “England’s troubles will increase until the bishops open Joanna Southcott’s box”.

Despite preparing a house for the purpose, the bishops never came. Although a psychic investigator claimed to have opened the box with the Bishop of Grantham — finding books, papers, dice, a lottery ticket, night cap, earrings, purse, and a pistol inside — it was too small to be Southcott’s. Today, the real box is hidden somewhere in the English town of Bedford, which the Panacea Society believed was the Garden of Eden. 

2. Vault B at the Sri Padmanabhaswamy Temple

Dedicated to Vishnu and run by royalty, the Sri Padmanabhaswamy Temple in Kerala, India is, because of its subterranean vaults, one of the most secure sacred sites in the world. The building is currently watched over by CCTV, metal detectors, and hundreds of guards armed with machine guns. Until June 2011, nobody even knew what treasures it concealed; it took a Supreme Court order to access to the “mega” secure vaults underground. 

Among the items found were: a solid gold idol of Mahavishnu, four feet high, three feet wide, and studded with diamonds and gems; a solid gold throne for an 18-foot idol of the god; thousands of gold chains (one 18 feet long); solid gold coconut shells studded with emeralds and rubies; golden elephants; and sacks full of gold coins from the Roman and medieval eras. The value of the haul tallied up to roughly $22 billion. 

However, one of the six vaults — Vault B — was exempt from the court order as it’s not part of the temple treasury. As of today, it remains unopened. But not through lack of trying. Apparently, one of the temple authorities’ attempts to crack the lock was halted when they heard the sound of crashing waves on the other side of the door — leading to the belief that it opens to the Arabian Sea. It’s also believed the vault is guarded by venomous snakes, vampires, and magic. There’s also rumored to be another, even more secret chamber beyond with solid gold walls and the largest cache of undiscovered treasure in the world.

1. The tomb of China’s first emperor

Ending the Warring States period, Qin Shi Huang united China under centralized imperial rule. Politically, this changed the Middle Kingdom forever. Personally, though, it boosted the new emperor’s lifelong obsession with immortality, affording him access to unprecedented resources and manpower. Even as a child, long before he became the first emperor, Qin Shi Huang was planning for this. Now he could issue edicts for everyone in the land to join his hunt for the elixir of life.

He could also start work on his underground necropolis, where (as a back-up) he planned for his body to lay in repose until it could be resurrected. Located in Shaanxi Province, this is where archeologists unearthed the famous Terracotta Army — lifesize replicas of ancient warriors. But this find, sizeable though it was, is only a tiny fraction of the 6.3-square-kilometer, and still unexplored, burial complex. 

Built by 700,000 men over the span of 38 years, the subterranean city is said to hide: picturesque palaces and towers; priceless artifacts; many, many more terracotta warriors than have so far been uncovered (and in their original purple too, undamaged by daylight); and a complete, mechanical replica of China’s river network — filled with mercury. This latter point is what has kept archaeologists at bay. According to the ancient historian Sima Qian, the tomb is also guarded by automatic crossbows — the precise details of which were intentionally lost to history when their creators were locked inside.
