Mesopotamian temples, known as ziggurats, were large, stepped structures built to honor the gods. These temples served as places of worship and were often located in the center of cities like Ur and Babylon. The ziggurats were made of mud bricks and featured multiple levels, with a shrine at the top where priests performed rituals. Inside the temples, offerings such as food and incense were made to the deities. The temples also housed priests who managed religious activities and maintained the temple's wealth. These structures played a crucial role in the spiritual and social life of ancient Mesopotamia.
