The Tower of Babel as told in Genesis 11:1–9 is an origin myth meant to explain why the world’s peoples speak different languages. According to the story, a united humanity in the generations following the Great Flood, speaking a single language and migrating eastward, comes to the land of Shinar.
There they agree to build a city and a tower tall enough to reach heaven. God, observing their city and tower, confounds their speech so that they can no longer understand each other, and scatters them around the world.
Some modern scholars have associated the Tower of Babel with known structures, notably the Etemenanki, a ziggurat dedicated to the Mesopotamian god Marduk by Nabopolassar, the king of Babylonia circa 610 BCE. The Great Ziggurat of Babylon was 91 metres (300 ft) in height.
Alexander the Great ordered it to be demolished circa 331 BCE in preparation for a reconstruction that his death forestalled. A Sumerian story with some similar elements is told in Enmerkar and the Lord of Aratta.
