Welcome to our odorous adventure – the top 10 incredible tour of scents that have shaped history, science, and even spirituality. From the mysterious perfume of the cosmos to the ethereal fragrance that surrounds saints, we’ll sniff our way through centuries of fascinating aromas, each backed by vivid anecdotes and scientific insight.

10 Space

Although space is a vacuum, astronauts have reported that it carries a surprisingly distinct bouquet. At the Milky Way’s core lies a massive cloud of ethyl formate, a chemical that smells like sweet, fruity rum. The origin of this aromatic mystery remains unexplained, but the scent has been noted by crew members who describe other space aromas as reminiscent of sulfur and meaty undertones. One astronaut, Thomas Jones, famously recounted, “When you repressurize the airlock and step out of the suit, there’s a clear ozone note, a faint acrid whiff, and something akin to burnt gunpowder or the electric ozone you smell around high‑voltage gear.”

Don Pettit, a veteran Science Officer aboard the International Space Station, offered his own poetic description: “The best way I can characterise it is metallic, a pleasantly sweet metallic aroma. It reminded me of long summer days welding heavy equipment, the sweet‑smelling fumes that drift from an arc‑welding torch.” His comparison paints space as a gentle, sweet‑metallic perfume rather than a sterile emptiness.

Technically, a vacuum cannot convey scent directly, yet countless microscopic particles float in the cosmos, adhering to suits and airlock filters, which then release their odorous signatures. NASA has even attempted to recreate this celestial perfume on Earth as part of astronaut training, allowing future explorers to experience the true smell of space before they launch.

9 Sundry Planets

Venturing beyond Earth, we can roughly infer the aromas of other planets by examining the chemical makeup of their atmospheres. Each world offers a unique olfactory fingerprint, dictated by gases, aerosols, and surface interactions.

Venus, cloaked in thick clouds of sulfuric acid, would likely exude a pungent, rotten‑egg smell. Similarly, Mars and Uranus host sulfur‑laden environments, with sulfur dioxide and hydrogen sulfide contributing to an unmistakable, fetid odor reminiscent of decaying eggs.

Jupiter’s massive, layered atmosphere creates a complex scent profile. In deeper layers, hydrogen cyanide could present a bitter‑almond aroma—an odor that, while toxic, is also found in certain flowers like jasmine when present as benzyl cyanide. Higher up, ammonia dominates, delivering a sharp, cleaning‑product‑like scent. These contrasting notes illustrate how a single planet can harbor multiple aromas depending on altitude.

The remaining planets, such as Saturn and Neptune, possess atmospheres composed mainly of odorless gases like hydrogen and helium, rendering them largely scent‑free to human perception.

8 Death

When a person approaches the end of life, a distinctive, often sweet‑fruity scent of acetone—commonly recognized from nail‑polish remover—can become prominent. This aroma may mingle with other disease‑related odors, creating a complex bouquet that signals the body’s final stages.

Following death, the body releases a suite of chemicals with evocative names: cadaverine and putrescine, both producing a powerful stench of rotting flesh and decay. Evolutionary biologists suggest these compounds act as warning signals, triggering a flight‑or‑fight response in nearby humans. Additional gases, such as hydrogen sulfide (rotten‑egg smell), skatole (fecal odor), methanethiol (rotten cabbage), and dimethyl sulfide (garlic), round out the macabre perfume.

Surprisingly, many of these foul‑smelling compounds are employed as food additives and even appear in certain perfumes, illustrating nature’s paradox where the same molecules attract insects to pollinate flowers and also entice human noses in culinary contexts.

7 Versailles Palace

First, let’s debunk the infamous myth that Marie Antoinette uttered “let them eat cake.” While that phrase has been widely repeated, the real story of Versailles is far more aromatic. The palace, a marvel of Baroque grandeur, also harboured an undercurrent of less‑refined scents: the occasional whiff of urine and excrement. Plumbing in the 18th century was rudimentary; only the royal chambers boasted flush toilets. Common folk relied on portable porcelain pots known as bourdaloues, and women, lacking undergarments, would lift their skirts to relieve themselves. Servants later cleaned up, but the lingering smell of waste mingled with smoke from faltering chimneys and the general bustle of a massive court.

Modern candle maker Cire Trudon captures this paradoxical ambiance in a luxury candle marketed as “the scent of Versailles floors.” Their description reads, “this regal perfume radiates vapours of wax, candelabra, and palace, weaving a sumptuous trail of incense through coniferous trees and citrus‑lit sunbeams.” While the candle itself is subtle and elegant, true authenticity still requires the addition of the palace’s inevitable “p”s—urine and feces—to fully recreate the historic atmosphere. The candle retails at around $100 on Amazon, a pricey homage to the scent of royalty.

Thus, walking through Versailles, one would encounter a layered olfactory experience: the refined fragrances of candles and incense interlaced with the unavoidable, earthy notes of human waste and smoky hearths, painting a vivid picture of royal life beyond the gilded veneer.

6 The Roman Colosseum

The ancient Roman Colosseum hosted spectacular spectacles: gladiatorial combat, exotic animal hunts, and, later, public executions. Bloodshed was inevitable, yet the Roman elite found the scent of fresh blood unpleasant. To mitigate this, architects installed a massive awning called the velarium, which shielded spectators from sun and rain. Ingeniously, hidden tubes sprayed perfumed water over the awning, delivering a fragrant mist that both cooled the audience and masked the odor of death.

These scented waters were often infused with saffron and verbena—ingredients later prohibited by the European Union for use in skin‑contact products. In addition to the awning’s mist, ornamental fountains released aromatic sprays, further enhancing the sensory experience. The result was a carefully curated atmosphere where the drama of the arena was accompanied by a subtle, pleasant fragrance, allowing spectators to enjoy the spectacle without being overwhelmed by the smell of violence.

5 Drugs

Throughout history, various natural substances have carried distinctive aromas that betray their chemical nature. While modern society often associates drugs with sterile pills, many retain potent, recognizable scents that can reveal their identity.

Opium, when smoked, releases a sweet, slightly burnt marshmallow fragrance, a scent that has been described as warm and comforting, reminiscent of a cozy fire.

Heroin, in contrast, gives off a strong vinegar odor when ignited. This sour smell derives from the acetic acid used during the drug’s synthesis, and the quality of heroin often correlates with the intensity of this vinegar note—higher‑purity products emit a fainter aroma.

Cocaine’s primary scent is methyl benzoate, a floral compound that provides a rich, tuberose‑like fragrance, also found in the tropical fruit feijoa. Drug detection dogs are trained to sniff out this chemical, alongside vinegar, to locate cocaine caches.

Methamphetamine, whether in crystal form or as crack, smells like burnt plastic combined with a sharp cleaning‑product aroma, similar to glass cleaner. Prolonged exposure can cause a person’s skin to exude an ammonia‑like scent, a tell‑tale sign of chronic use.

4 The Titanic

On the fateful night of April 15, 1912, the Titanic’s interior was awash with a blend of luxurious and industrial aromas. Fresh varnish, newly poured paint, and the scent of freshly cut wood greeted first‑class passengers as they boarded. The ship’s coal‑driven engines emitted a steady plume of smoke, while the galley served roasted duck, lamb, and beef, filling the grand dining rooms with mouth‑watering aromas.

That same year, the renowned French perfume house Guerlain introduced “L’Heure Bleue,” a fragrance described as velvety, soft, and romantic—evoking the twilight hour before stars appear. This perfume, coveted by elite women aboard the Titanic, would have added a subtle floral‑citrus layer to the ship’s overall scent profile, intertwining luxury with the maritime environment.

As the night progressed, a chilling metallic scent emerged—the odor of the iceberg itself. Ice, like a freezer, absorbs surrounding aromas; the iceberg that struck the Titanic carried a mineral, slightly metallic fragrance, tinged with the chemical signatures of the sea and marine life. Recognising this faint metallic whiff might not have saved the vessel, but it underscores how even frozen masses convey a distinct olfactory signature.

3 Ancient Egyptian Temples

My fascination with Ancient Egypt leads me to the fragrant heart of its temples. Visitors to these sacred spaces would first encounter the rich, heady perfume of frankincense and myrrh, the same resins that still scent modern churches. These incense clouds would mingle with a bouquet of lotus blossoms, marsh reeds, and other aquatic flora. The lotus emitted an intensely sweet, fruit‑like fragrance, while the surrounding marsh plants added a damp, earthy undertone.

Interwoven among these scents were jasmine’s hypnotic, slightly fecal indole note, the sweet perfume of roses, and the robust, tobacco‑like aroma of fresh mandrake. Together, they created a layered olfactory tapestry that was both intoxicating and spiritually resonant.

Food offerings further enriched the temple’s aroma profile. Freshly baked bread and roasted meats added a warm, homely scent reminiscent of holiday feasts in a modern village. Seasonal offerings of milk, herbs, and vegetables introduced faintly sour or even rancid notes, completing the sensory experience of devotion, community, and the divine.

2 The Holocaust

In 1942, the Nazi regime began deporting Jews via overcrowded trains that offered no stops for bathroom breaks or medical care. The cramped, unsanitary conditions produced an overwhelming stench of vomit, feces, and urine, creating a nightmarish olfactory landscape that underscored the dehumanising horror of the transports.

Those who witnessed the crematoria later described an unprecedented smell. While cooking meat releases a familiar, appetising scent, the combustion of human flesh produced a sickening combination: a beef‑like odor from burnt muscle, a pork‑like aroma from human fat, and pungent sulfur notes from burning hair and nails. A metallic, coppery smell emanated from searing blood and iron‑rich organs, while the burning of spinal fluid released a sweet, musky fragrance reminiscent of perfume—an unsettlingly beautiful contrast to the surrounding death.

American soldiers arriving at liberated camps reported that the odor of death and human waste spread for miles, a pungent cloud that signalled disease and devastation. One private noted, “The smell covered the entire countryside… disease—typhus, dysentery, tuberculosis—was universal.” The relentless stench of cremation and excrement lingered long after the fires were extinguished, imprinting an indelible sensory memory of the atrocities.

1 Sanctity

Saints have been said to emit a special fragrance, often described as the opposite of sulfurous decay. This “odor of sanctity,” known in Latin as osmogenesia, can manifest in several ways: some saints exude a sweet perfume after death, others radiate a fragrant aura while alive, and a few release scented liquids from their tombs. A striking example is St. Simeon Stylites, who spent 37 years atop a pillar; after his death, witnesses reported a perfume‑like scent surrounding his remains.

Accounts of sanctified aromas consistently highlight sweet, heavenly notes: honey, butter, roses, violets, frankincense, myrrh, pipe tobacco, jasmine, and lilies. The scent is often described as otherworldly, evoking a sense of divine presence. For instance, St. Polycarp’s martyrdom supposedly filled the air with incense, while St. Thérèse of Lisieux’s incorrupt body was said to smell of roses, lilies, and violets. Even the wounds of stigmata are reported to give off a holy fragrance, reinforcing the belief that purity can be sensed through smell.

The majority of people know that humanity’s past was far from spotless. Between eyebrow‑crafting from mouse skin, a British king who swore bathing would ruin his health, the Romans’ love affair with lye (a blend of ash and urine) for laundry, and the millennia‑long wait for toilet paper, our hygiene record reads like a comedy of errors. What most folks overlook, however, are the downright odd aromas that wafted through 18th‑century England. Brace yourself for the top 10 bizarre odours that defined Georgian life.

Why the Top 10 Bizarre Scents Still Fascinate Us

9 Tobacco

When Georgian England erupted with social activity, pipe‑smoking was the badge of a gentleman’s leisure. By the early 1700s, however, tobacco earned a sour reputation. Women were thought to be especially sensitive to the fumes, and a pipe‑laden husband risked his marriage. Public puffing became a breach of etiquette, and the genteel class frowned upon the cloud of smoke invading drawing‑rooms.

Enter snuff – the fashionable alternative of inhaling finely ground tobacco through the nostril. While it spared everyone a smoky haze, snuff came with its own chorus of coughs, grunts and spitting. Its chief advantage was that the scent stayed close to the user, sparing unsuspecting bystanders. Yet even this discreet habit sparked complaints; churchgoers muttered about the noisy snortings that punctuated sermons.

8 Fish

Georgian marketplaces were a far cry from today’s sanitized supermarkets. With no packaging, expiry dates, or health regulations, buyers lived by the motto “caveat emptor.” To avoid the dreaded stomach‑upset, households printed manuals teaching citizens how to judge food by scent. A fish or cut of meat emitting a slick, “slimy” odor was a clear sign to steer clear.

Even game birds weren’t exempt; pheasants were examined around the neck for a “tainted” whiff, while butter required a personal knife for testing, lest a merchant hand over the choicest slice. The Billingsgate women, famed for vending fish, were notorious for their sweaty demeanor and sharp tongues, making the sniff‑test feel like an insult to their credibility.

Consequently, many Georgians refused to partake in the ritual of smelling their purchases, deeming it an affront to the seller’s honor. The very act of testing turned a simple market visit into a socially charged performance.

7 Paint

Although it may seem odd to rank paint among the most memorable aromas, Georgian diarists frequently lamented its pungency. Redecorating was a rare, almost ceremonial event, so the sharp, oily perfume of linseed‑oil and turpentine lingered long after the brushes were put away.

The Italian physician Bernardino Ramazzini observed that painters often lost their sense of smell from prolonged exposure to these chemicals. So enthralled was he by the world of odours that he advocated writing a comprehensive “natural and physical history of odors.”

6 Ammonia

The scent of ammonia is unmistakable, a sharp sting that instantly alerts the trigeminal nerve – the same nerve that governs facial expressions. In Georgian England, ammonia was harvested from fermenting urine and became a popular “reviver of the senses.”

Society placed a premium on a keen nervous system; a “sensitive nerve” was a mark of refinement, especially among women, who were thought to be prone to anxiety. Novels and stage plays of the era even featured heroines daringly inhaling corked bottles of ammonia to sharpen their wits. Smelling salts, essentially concentrated ammonia, were touted as lifesavers for the drowned or asphyxiated.

Ammonia wasn’t the only odd stimulant. Some adventurous souls experimented with pumping tobacco smoke up the rear – a bizarre, and decidedly unpleasant, method of “waking up” that made the era’s medical folklore all the more colorful.

5 Marzipan

The Industrial Revolution coincided with a surge in urban living, giving city‑dwelling Georgians access to exotic ingredients. Marzipan, a confection of ground almonds, sugar, and rose water, quickly became a favourite. Its sweet, nutty aroma signalled the end of a meal, and the treat was affordable enough to appear on many a household table.

Beyond its culinary appeal, marzipan was sculpted into miniature figures – people, animals, even tiny castles – that graced dining tables as decorative centrepieces. These edible sculptures added a fragrant flourish to Georgian banquets, marrying taste and art in a single bite.

4 Wigs

While marzipan provided sweet décor, Georgian wigs were true works of hair‑craft. Hair was piled onto pads and wire frames, then blended with horsehair to achieve towering styles. The 1760s favored an egg‑shaped silhouette that later stretched into the iconic pouf.

The Duchess of Devonshire made headlines with a three‑foot tower of hair, studded with stuffed birds, waxed fruit, and even model ships. Such extravagance came at a steep price, and the wigs were often worn for weeks without washing. Inevitably, insects took up residence, prompting women to fashion scratching rods to dislodge the unwelcome tenants.

3 Body Odor

Georgians lived in a paradox of glamour and grime. While daily splashes of water refreshed faces and hands, a full‑body wash was deemed harmful to health. Women’s heavy gowns trapped sweat, and without modern deodorants the resulting stink could be overwhelming.

Clothing was rarely laundered – a dress might see a wash only once a month, while under‑garments were changed more frequently but cleaned with the same lye mixture the Romans used for laundry. The combination of sweat, infrequent washing, and harsh cleaning agents created a formidable, lingering body odor that defined the era’s private scentscape.

2 Bad Breath

Georgians also grappled with a less pleasant oral aroma. Early tooth‑powders contained sulfuric acid, which stripped enamel and left a harsh chemical aftertaste. To combat the foul breath, people chewed herbs or swallowed parsley, hoping the fresh scent would mask the rot.

When a tooth became hopeless, it was yanked from the gum with pliers – no anesthetic, just raw determination. Some sought porcelain replacements, while others, often impoverished, sold their own teeth to make a living, turning dental decay into a grim marketplace.

1 Bodily Fluids

The mystery of Georgian women’s sanitation remains a puzzling chapter in history. Without modern undergarments, they relied on nature and a porcelain jug called a bourdaloue, clutched between the thighs beneath their skirts. Remarkably, ladies could continue conversing while relieving themselves, turning a private act into a public performance.

These ten distinct scents – from lingering bodily fluids to the lingering sweet whiff of marzipan – paint a vivid picture of a time when personal hygiene was a communal concern. Though today scented wigs are rarer, body odor and bad breath persist, now mitigated by showers and deodorants.

Top 10 incredible smells that will blow your mind – a lingering reminder that even centuries later, our noses remember the past.
