Originally 91 meters in height, little remains of it now except ruins.
Etemenanki is considered the possible inspiration to the biblical story of the Tower of Babel.
It is unclear exactly when Etemenanki was first built. A review article by Andrew R. George says that its builder may have "reigned in the fourteenth, twelfth, eleventh or ninth century [BC]" but argues that
The city of Babylon had been destroyed in 689 BCE by Sennacherib, who claims to have destroyed the Etemenanki. The city was restored by Nabopolassar and his son Nebuchadnezzar II. It took 88 years to rebuild the city; its central feature was the temple of Marduk (Esagila), with which the Etemenanki ziggurat was associated. The ziggurat was rebuilt by Nebuchadnezzar II. The seven stories of the ziggurat reached a height of 91 meters, according to a tablet from Uruk (see below), and contained a temple shrine at the top.
