Lothal is a lost city in India—once part of the ancient Indus Valley civilization. However, Lothal isn't completely lost. A portion of the city has been discovered and excavated, and yet it is still steeped in mystery.

Part of the superstition surrounding Lothal has to do with its name, which means "the mound of the dead." According to speculation, the city was once an important center for farming, trade, and capitalism. However, the fate of Lothal—and why the city fell to ruin—remains unknown.

As sensational and alluring as the story of Atlantis is, there is a good chance that it's simply one of Plato's fictional tales. According to the philosopher, Atlantis was quite sizable—comparable to northern Africa and part of Turkey.

Also known as the Atlantis of the Sands, the city of Ubar is one of Dubai's greatest legends. As the story goes, God brought it to ruin, and it remains lost beneath the desert sands.

Archaologists have speculated that Ubar may have been more like a region than a city. The estimated time period ranges from 2,800 BC to 300 AD.

Some believe that the ruins of Shisr might actually be Ubar, but there's still no way to authenticate this theory.

The Greek explorer Pytheas is responsible for the legend of Thule. He described a mystical land where the sun doesn't set in the summer and never rises in the winter. 

Thule: It Was A Mystery To Them

Pytheas’s account of Thule closely matched the landscapes of Nordic lands—yet for Mediterranean peoples of his era, it remained an enigmatic and distant mystery.

Therefore, many believe that Pytheas was simply describing what we know now as Greenland or Iceland. Others, however, aren't too sure—and theorize that the real Thule is still out there.

Aztlan

Aztlan is considered the origin place of the Aztecs—but it has never been found. Its name means "place of herons" or "place of whiteness," which coincides with the stunning descriptions of the city.

Aztlan was supposedly a gorgeous island known for its wildlife. The waters were rich with gorgeous fish, while duck and herons roamed the land. There were also colorful birds. So what happened to this rich city?

Legend says that when the people of Aztlan migrated to the Valley of Mexico, their city vanished into the shadows of time. Despite countless searches in Western Mexico and Utah, its whereabouts remain a mystery.

Located off the coast of North Carolina, the Roanake Colony was founded in 1585—but these days, it's better known as the Lost Colony.

In 1590, a supply ship returned to the colony, only to make a disturbing discovery: all of the inhabitants had vanished. However, there was one clue left behind.

Chillingly, someone had carved a word into one of the posts, reading "Croatoan." The disappearance of the colonists sparked some chilling theories.

Some believed the colonists were wiped out by Native Americans, while others suspected they had blended into local tribes. A few even speculated pirates had taken them captive.

The city was said to be one of Mesopotamia's biggest trading partners, but its exact location has always been a mystery. Some argued that it was near the Arabian Gulf, but today, many think it was closer to Bahrain—even stretching to Qatar, Kuwait, and easter Saudia Arabia.

In historical texts, Dilmun existed between 3,300 BC and 556 BC. However, archeologists have not yet found a site that matches this timeline.

Cahokia remains one of America’s greatest mysteries—a thriving city that flourished long before Columbus ever set foot in the West, located where southern Illinois stands today.

Established by Native Americans, Cahokia was a sophisticated place of farming, hunting, and trade. They even had urban planners who mapped out the city based on astronomical alignments.
