A ziggurat is a pyramidal and stepped tower that is both an architectural and religious structure. It was an essential part of the major cities of Mesopotamia from approximately 2,200 until 500 BCE.
The main elements of a Ziggurat include the temple, drain, outer shell, gate, and weep holes.
It is a terraced pyramid-like structure consisting of multiple levels or platforms, each smaller than the one below it, creating a stepped or tiered shape. The word "ziggurat" comes from the Akkadian language, and it means "to build on a raised area.” The structure of a ziggurat typically consisted of a rectangular or square base, with each level or terrace getting smaller as it ascended. The access to the higher levels was often provided by a central staircase or ramp. At the top of the ziggurat, there was usually a shrine or a temple.
