35. The Voynich Manuscript
In the vaults of Yale University’s rare book library lies an enigma that has puzzled cryptographers and scholars for decades. Known as the Voynich Manuscript, this 15th-century book is filled with unknown symbols and bizarre illustrations of imaginary plants and celestial diagrams. Despite the best efforts of World War II codebreakers and modern computer algorithms, no one has yet deciphered its contents. Could it be an elaborate hoax, or does it hold the secrets of a long-lost alchemical tradition?
34. The Lost Colony of Roanoke
The mystery of Roanoke, where an entire colony disappeared without a trace, continues to intrigue. In 1587, 115 settlers landed on Roanoke Island, now part of North Carolina, only for every single person to vanish by 1590. The only clue left behind was the word “CROATOAN” carved into a tree. Despite numerous theories ranging from a massacre to assimilation with local tribes, the fate of the Roanoke settlers remains one of America’s most haunting historical puzzles.
33. The Nazca Lines
Spread across the arid plains of Peru, the Nazca Lines are a series of large ancient geoglyphs that include clear shapes of animals, plants, and geometric figures.

Why our Neolithic ancestors erected these structures, and why they went to such lengths to hide them, remains a puzzle that could drastically alter our understanding of prehistoric humanity.
28. The Atlantis Legend
The legend of Atlantis, a technologically advanced civilization said to have sunk into the ocean “in a single day and night of misfortune,” has captured the imagination of explorers and historians for centuries. First mentioned by Plato, who used it as an allegory on hubris, the search for the physical remains of this city has spanned the globe, from the Mediterranean Sea to the Caribbean. Yet, despite numerous theories and expeditions, no definitive evidence has been found to prove Atlantis ever existed. Is it merely a myth, or a lost piece of human history lying beneath the waves?
27. The Tomb of Genghis Khan
The final resting place of Genghis Khan, the emperor who created one of the largest empires in history, has eluded historians and treasure hunters alike. Legend has it that the burial party killed anyone they encountered after the burial to keep the location secret, then committed suicide to seal the secret forever. Despite numerous searches and scientific studies, the location of the tomb remains one of Mongolia’s most enduring mysteries.
26. The Shugborough Inscription
On the grounds of Shugborough Hall in Staffordshire, England, stands an 18th-century monument known as the Shepherd’s Monument. It features a carved relief copying Nicolas Poussin’s painting, “The Shepherds of Arcadia,” but beneath it is a sequence of letters: O.U.O.S.V.A.V.V. These letters have confounded decipherers from amateur sleuths to professional cryptologists, including those from Bletchley Park. Some speculate it’s a coded message leading to the Holy Grail, others believe it’s a love note, but its true meaning remains undiscovered.
25. The Giant Stone Jars of Laos
Scattered across the Xieng Khouang plain in Laos are thousands of giant stone jars, some as tall as three meters and weighing over several tons. Known as the Plain of Jars, archaeologists believe these stone containers, dating back to the Iron Age (500 BCE to 500 CE), were used for burial practices.

In July 1518, residents of Strasbourg (then part of the Holy Roman Empire) were struck by a sudden and uncontrollable urge to dance. The “dancing plague” took hold of many people, with dozens dancing for days without rest, and some reportedly dancing to their deaths from heart attack, stroke, or exhaustion. Historical documents recount this bizarre phenomenon, yet modern science has not definitively explained these events. Was it mass hysteria, a medical condition, or perhaps something more esoteric?
15. The Green Children of Woolpit
In the 12th century, two children with green-tinted skin reportedly appeared in the village of Woolpit in Suffolk, England. Speaking an unknown language and refusing all food except beans, these children eventually adapted to normal food, lost their green color, and integrated into society. The girl, who survived longer than her brother, eventually described coming from a place with no sunlight. While considered a folk tale, the story persists in discussions about parallel universes, extraterrestrial visitation, and biochemical anomalies.
14. The Lost Roman Legion
After their defeat in the Battle of Carrhae in 53 BCE, about 10,000 Roman soldiers were captured by the Parthians and disappeared into the mists of history. Later stories suggest that these soldiers were relocated to fight along the eastern frontier of the Parthian Empire and might have been the forefathers of a Roman-style city found in China, hinting at a remarkable journey from the Roman Empire to the heart of Asia. The true fate of these Roman legions remains a blend of history, myth, and speculation.
13. The Jonestown Audio Recordings
During the last hours of the Jonestown commune, led by Jim Jones, in Guyana in 1978, a series of chilling audio recordings were made, documenting the mass suicide and murder of over 900 people through enforced cyanide poisoning. The tapes provide a haunting insight into the control Jones had over his followers and the chaotic and tragic end. Yet, they leave many questions unanswered about the extent of coercion and the psychological mechanisms at play in what became one of the largest mass deaths in a single event in modern history.
12. The Lake Anjikuni Disappearance
In November 1930, an entire Inuit village near Lake Anjikuni in Canada was reportedly found abandoned by a fur trapper. The villagers’ disappearance was accompanied by eerie findings: untouched meals, abandoned clothing, and a dead fire. The Royal Canadian Mounted Police investigated, but no trace of the villagers was ever found, leading to speculation about supernatural explanations or mass abduction. The mystery of what happened at Lake Anjikuni continues to intrigue and perplex.
