The high temple was a special type of temple that was home to the patron god of the city. Functionally, it served as a storage and distribution centre as well as housing the priesthood. The White Temple of Anu in Uruk is typical of a high temple which was built very high on a platform of adobe-brick. In the Early Dynastic period high temples began to include a ziggurat, a series of platforms creating a stepped pyramid. Such ziggurats may have been the inspiration for the Biblical Tower of Babel.
