Worldwide Mysteries. Alexander The Great.

By the age of 32, Alexander the Great had swept across Asia, conquering a region from the Balkans to Pakistan and ruling over the biggest empire in the ancient world. Then, in 323 B.C., he died, and his empire fell like a house of cards. The ruler was felled by an illness in Babylon. Historical documents suggest one of his generals brought his body back to ancient Egypt two years later and that his body was held in the city of Memphis while a tomb was built for him in Alexandria.

However, no one knows exactly where that iconic tomb is located. Some have suggested it has sunk beneath the waves, because it was built in the “Palaces District” that is now submerged. If that’s the case, it may have been destroyed by millennia of both human and natural forces, experts previously told Live Science. Even if it were to be found, there would likely be few identifying marks proving the tomb belonged to Alexander. The ancient historians who described the building of the tomb left little physical description of it, so researchers may need an intact inscription to identify the tomb.
