Stretching from Miami to Bermuda and Puerto Rico, this loosely defined region in the Western part of the North Atlantic Ocean has gained notoriety for numerous aircraft and ship disappearances. This has led to various theories, including magnetic anomalies, extraterrestrial activities, and underwater anomalies. However, many scientists dismiss the notion of any nefariousness, attributing incidents to human error, natural disasters, and the area's heavy maritime and air traffic. Despite efforts to debunk myths surrounding the Bermuda Triangle, its reputation as a dangerous zone persists in popular culture, fueling speculation and fascination.

In 1587, the Roanoke Colony, led by Governor John White, was established on Roanoke Island, North Carolina. White returned to England for supplies that year, but when he came back in 1590, the entire colony had essentially disappeared. The only real clue was the word "Croatoan" carved on a post. The fate of the colonists, approximately 115 individuals, remains unknown to this day. Theories include assimilation with the Croatoan tribe or struggles for survival.

Renowned for their distinctive white mantles adorned with a red cross, the Templars developed a sophisticated financial system, becoming early bankers. In 1312, Pope Clement V disbanded the order under pressure from King Philip IV of France, leading to arrests, trials, and the execution of many Templars. Legends and conspiracy theories about them persist, often linking them to the Holy Grail.

Speaking of the Grail, this legendary and elusive artifact in Christian mythology has enraptured imaginations for centuries. The chalice Jesus used at The Last Supper, which is what the Grail is usually purported to be, embodies both spiritual significance and magical qualities. Countless medieval tales, including Arthurian legends, depict knights embarking on quests to find this sacred vessel, often encountering trials and supernatural elements. The Grail's nature and location remain disputed, and many modern literary and cinematic explorations are still based on its myth and legend.

Another iconic relic of religion, the Turin Shroud is a linen cloth, approximately 14 feet long, bearing the image of a man believed by some to be Jesus Christ. The cloth displays a faint front-and-back image of a man with wounds consistent with crucifixion. While some consider it an authentic burial cloth of Jesus, debates persist over its origin and authenticity. Carbon dating in 1988 revealed the overwhelming probability that the Shroud was actually a medieval creation, but some people of faith still believe that there is more to the story of the Shroud’s origin.

A devastating pandemic swept through Europe in the mid-14th century. The Plague resulted in unparalleled mortality rates. It is estimated to have wiped out 30 to 60% of Europe's population between 1347 and 1351. While the Black Death's cause is now identified as the Yersinia pestis bacterium, certain aspects of its historical impact remain contentious. Questions persist about why some individuals seemingly had immunity, the true extent of mortality rates, and the precise mechanisms of the pandemic's rapid spread. Additionally, the origins of the plague in Asia and its journey to Europe are not entirely clear.

This medieval manuscript stands as one of the world's greatest linguistic and historical puzzles.

A prehistoric monument located on Salisbury Plain in England, Stonehenge is an icon that has puzzled researchers for centuries. Constructed around 3000 BCE, its purpose, builders, and the methods used to transport its massive stones, remain unclear. The arrangement of standing stones in a circular pattern suggests astronomical significance, possibly aligning with celestial events. The mystery deepens with the origins of the bluestones, transported from Wales over 150 miles away. The spiritual and ritualistic aspects of Stonehenge add layers to its allure.

The identity of the infamous killer active in the Whitechapel district of London in 1888 remains a gruesome riddle. The Ripper murdered at least five women, leaving a horrible trail of brutality that has inspired much disgusted fascination over the past century and a half. The killer's true identity has never been conclusively established, fueling a constraint stream of speculation. The lack of definitive evidence, the taunting letters sent to the media, and the Victorian setting have all contributed to the ongoing cold-case theorizing of historians, detectives, and amateur sleuths.

A mythical island first mentioned by ancient Greek philosopher Plato in his dialogues has become one of history's greatest obsessions. Described as a prosperous and advanced civilization, Atlantis supposedly sank into the ocean in a catastrophic event. The lack of concrete evidence and the allegorical nature of Plato's accounts have fueled speculation about the existence and location of Atlantis. Numerous proposed locations range from the Mediterranean down to Antarctica. Whether Atlantis was a real place, a metaphor, or a product of ancient imagination, the idea of a lost civilization beneath the waves remains enticing.

Dancing is normally a very healthy activity. But not this time. In the town of Strasbourg, France in 1518, people began involuntarily dancing in the streets, unable to stop for days — or even weeks. The dancing phenomenon spread widely, ultimately affecting around 400 individuals. Some danced to exhaustion, including collapsing or even dying. The cause of what came to be called a plague remains uncertain, with explanations ranging from mass hysteria to poisoning or infection of some kind. Records from the time provide limited explanations, leaving the Dancing Plague as a bizarre and unexplained event.

An American merchant ship was discovered adrift and deserted in the Atlantic Ocean in 1872. Its crew of seven and the captain's family vanished without a trace. The ship's cargo and belongings, including provisions and personal items, were left undisturbed, and no signs of violence or foul play were evident. The mystery deepened with the absence of a distress call or clear reason for abandonment. Was it piracy? Or mutiny? Other potential explanations put forward include natural disasters or seaquakes. But what happened to the Mary Celeste is still lost in time.

A huge explosion occurred in Siberia on June 30, 1908. A massive blast, equivalent to 10 to 15 megatons of TNT, flattened around 80 million trees over 830 square miles. Eyewitnesses reported a fireball and shockwave, but no impact crater was found. Convincing theories include a comet or asteroid explosion, but conclusive evidence has proven difficult to find. Its lack of a clear cause, and the absence of a particular celestial body, continue to intrigue scientists. Unpredictable and powerful forces at play in the cosmos still can — literally — impact us.

Modernity also holds more mysteries. The disappearance of Malaysia Airlines Flight MH370 on March 8, 2014, remains one of the most affecting. The aircraft, en route from Kuala Lumpur to Beijing, lost contact with air traffic control and disappeared from radar screens.
