One of the most important aspects of Babylonian religion and tradition, and probably the best known, is the ziggurat.Ziggurats were built to reach nearer the heavens. This was so the gods could be contacted and worshiped.
The Babylonians gave rich offerings to the gods and built splendid temples. Similarly they built ziggurats. The size and splendor of a ziggurat would show the city and king’s devotion to the particular city god being worshiped. They might have temples to other gods but they would only have a ziggurat to the city god.
