top 10 remarkable Highlights from Bulgaria
10 Bulgaria’s Last Aurochs
Modern domestic cattle are descendants of a fearsome wild ancestor known as the aurochs. These massive bovines could tip the scales at around 1,100 kilograms (2,425 lb) and sported massive, lethal horns that matched their notoriously temperamental disposition. The species survived in Poland until 1627, but historians already recorded its disappearance from Bulgarian lands as far back as the 12th century.
Fast‑forward to 2017, when archaeologists digging at the famed Rusocastro Fortress uncovered a mixed assemblage of animal bones dating to the 13th–14th centuries. Among the domestic cattle and other wildlife, they identified the unmistakable remains of aurochs—proof that a small, isolated herd survived far longer than previously believed, extending the medieval range of the species well beyond Poland, Belarus and Lithuania.
The Rusocastro find reshapes our map of medieval aurochs distribution, showing that the fortress’s inhabitants hunted these formidable beasts despite the difficulty of the chase. Analyses suggest that wild meat accounted for roughly a quarter of the bone assemblage, indicating a surprisingly high reliance on aurochs meat at the stronghold.
9 A Chariot With Horses
In the summer of 2008, a Bulgarian archaeological team uncovered a wooden chariot buried deep within ancient Thrace. The vehicle wasn’t alone—two horses lay in front of it as if poised to pull the carriage, and a loyal dog was also interred nearby, creating a dramatic tableau of ancient transportation.
A year later, the same team exposed the tomb of the chariot’s owner: a brick‑lined burial chamber that housed a man who had met his end roughly 1,800–2,000 years ago. Grave goods—including gold rings, silver coins, a silver cup emblazoned with the Greek god Eros, and armor‑type attire—point to a Thracian noble or tribal leader of considerable status.
The chariot itself was sheathed in bronze, its once‑vibrant mythological scenes now faded beyond recognition. Such elaborate burials began as early as 2,500 years ago and reached their zenith during the Roman period, roughly 2,100–1,500 years ago, when the practice spread across the empire.
While chariot interments appear in other Roman territories, none match the enduring popularity they enjoyed in Thrace, where the tradition persisted far longer and produced some of the most spectacular discoveries.
8 Mystery Arrow
In 2017, workers at Plovdiv’s ancient Odeon—once a Roman stage for theatrical performances—stumbled upon a medieval burial beneath the stone seats. The upper layers contained ceramics that dated the grave to the 11th–12th centuries.
Inside the tomb lay a skeleton of indeterminate gender, with a single arrow lodged firmly in the chest. Over the centuries, the bones had become jumbled, making it difficult for researchers to determine whether the shaft was originally placed there or had simply been left after a fatal wound.
One plausible explanation is that the arrow was a ceremonial offering, a practice known from several ancient burial rites where warriors were equipped with weapons for use in the afterlife.
Alternatively, the individual may have died from a stray shot, and the arrow remained untouched during interment. The ambiguity adds a layer of intrigue to an otherwise straightforward medieval grave.
7 The Golden Mask
Just as Egypt boasts its Valley of the Kings, Bulgaria shelters its own “Valley of the Kings,” a landscape dotted with Thracian burial mounds. In 2004, archaeologists uncovered a massive tomb constructed from six stone slabs that together weighed nearly 12 tons.
The true marvel, however, was a solid gold death mask discovered inside the tomb. Weighing a modest 0.45 kilograms (1 lb), the mask proved that the Thracians possessed sophisticated metalworking skills comparable to those of their Greek and Egyptian contemporaries.
Dating back roughly 2,400 years, the mask and its imposing tomb demonstrate that the Thracian culture was a major force in the ancient world, commanding territories that stretched across modern‑day Bulgaria, Macedonia, Romania, Turkey, and Greece.
This find underscores the fact that great ancient civilizations were not limited to the Mediterranean basin; the Thracians left a legacy of artistry and power that rivals the most famous archaeological sites.
6 A Roman Bath House
In 2016, a vigilant archaeologist driving past a construction site in Plovdiv spotted ancient Roman tiles amidst the modern rubble. Unfortunately, workers had already begun dismantling a valuable wall before the discovery was reported.
Plovdiv’s municipal authorities swiftly ordered emergency excavations, uncovering the city’s most impressive find of the year: the pristine walls of a Roman thermae, a public bathhouse of considerable size and architectural sophistication.
The thermae, built in the second century AD, joins other celebrated Plovdiv landmarks such as the Antiquity Theatre and the Ancient Roman Stadium, illustrating the city’s rich imperial heritage.
Because the surrounding area is densely populated with private property, further archaeological work is challenging, leaving many potential secrets of the ancient city still buried beneath modern homes.
5 Two‑Millennia‑Old Ship
One might assume that a wooden vessel sunk two thousand years ago would have long since disintegrated, yet a remarkably preserved Roman ship was recovered from the Black Sea’s depths among a fleet of sixty wrecks spanning multiple eras.
Discovered in 2017, the ship stood out for its intact mast, dual quarter‑rudders, and full set of yards. Inside the hull, archaeologists found 2,000‑year‑old rope, a cargo of amphorae in the bow, cooking pots, and even a capstan—an on‑deck device previously known only from ancient illustrations.
The ship’s exceptional state of preservation is owed to the Black Sea’s anoxic water column. Below about 150 meters (500 ft), oxygen‑depleting conditions prevent wood‑eating organisms from thriving, effectively “pickling” the timbers and allowing centuries‑old shipbuilding techniques to survive.
This underwater treasure provides a rare glimpse into Roman maritime engineering and trade networks that once crisscrossed the ancient world.
4 Europe’s Oldest Town
Excavations in 2012 uncovered Europe’s oldest known prehistoric settlement in northeast Bulgaria, a community of salt specialists who boiled spring water to produce solid bricks of salt—an incredibly valuable commodity in antiquity.
Archaeologists uncovered a formidable stone wall encircling the town, constructed between 4,700 and 4,200 BC, likely erected to protect the lucrative salt sources from rival groups.
The settlement housed roughly 350 inhabitants who lived in two‑story homes, performed ritual activities in ceremonial pits, and buried their dead in a modest cemetery. Remarkably, the site predates classical Greek culture by about 1,500 years.
Just a few decades ago, a gold cache—now recognized as the world’s oldest—was discovered 35 km (22 mi) from the fortified town, hinting at a broader network of prehistoric mining and trade across the Balkans.
3 The Kazanlak Treasure
In 2017, police pulled over a vehicle in the town of Kazanlak for suspicious behavior, unaware that they were about to intercept a cache of priceless artifacts destined for the black market.
Bulgaria’s rampant looting problem—estimated at $1 billion annually—means that many treasures vanish without a trace. The seized haul, concealed in a wooden box, contained roughly three kilograms (6.6 lb) of gold and semi‑precious ornaments, including earrings, a tiara, a bracelet, coins, and a necklace, accompanied by pottery shards and a tombstone.
Among the items were detonators, suggesting that the thieves used explosive methods to “excavate” the treasure, a destructive practice that threatens the integrity of archaeological sites.
Because the smugglers refused to reveal the find’s origin, experts hypothesize that the collection once belonged to a high‑status woman from Kran, a medieval city in the same region, though the exact burial context remains a mystery.
2 The Baptist Bones
In 2010, a pair of archaeologists exploring the island of Sveti Ivan (“Saint John”) in Bulgaria uncovered a sarcophagus near a stone box inscribed with the name of John the Baptist and his feast day, June 24.
The burial yielded only a handful of human remains—a knucklebone, an arm bone, a single tooth, a rib, and a fragment of skull—yet these fragments were sufficient for radiocarbon dating, which placed the individual in the early first century, roughly aligning with the biblical timeline of John’s life.
Further analysis indicated that the bones likely originated from the Middle East, reinforcing the tantalizing possibility that the remains could belong to the biblical figure himself.
Complicating the picture, three animal bones—a cow, a horse, and a sheep—were found alongside the human remains, each dating to about 400 years older than the human bones, a puzzling discrepancy that researchers have yet to explain.
1 Oldest Multiple‑Page Book
An anonymous donor presented a striking artifact to Bulgaria’s National History Museum: a bound book fashioned entirely from gold, making it the earliest known example of a multi‑page codex.
The six‑page manuscript, each leaf composed of 24‑carat gold, features intricate illustrations of a mermaid, a harp, a mounted rider, and soldiers, and is written in a lost Etruscan language, linking it to a civilization that vanished after Roman conquest.
The donor claimed he discovered the treasure as a young man while a canal was being dug in southwestern Bulgaria, uncovering a tomb that held the golden book. He kept the artifact for six decades before finally handing it over to the museum.
Scientific authentication confirmed the manuscript’s age at roughly 2,500 years, and while about 30 similar gold sheets exist worldwide, none are bound, making this find uniquely precious.
