When was the Sumerian Ziggurat built?
The role it played was the center of Sumerian lives. Sumerians worshiped gods in the temple, called a ziggurat, and that's why the ziggurat is the largest structure and in the center of the village. The ziggurat gave Sumerians a place to worship their gods, who they believe can prevent disasters and created humans to serve them, so that's their main purpose in life. This was the role the temple played in Sumerian society.
