A temple built on a series of stages from a square base on which there was a sanctuary. The god was supposed to reside at the top. There were ziggurats at Nineveh, Babylon (built between 1900 and 1600 BCE), and Ur, and it is thought that the narrative of the tower of Babel (Gen. 11: 1–9) may have been inspired by a neighbouring ziggurat in Mesopotamia. Jacob's dream of a staircase (Gen. 28: 12–15) may have been triggered by seeing such a building.
