Where did ziggurats came from?

Ziggurats originated in ancient Mesopotamia, specifically in regions that are now part of modern-day Iraq. These massive, tiered structures date back to around the 3rd millennium BCE and were primarily built as temples dedicated to the gods of the Sumerian, Akkadian, Babylonian, and Assyrian cultures. Their design reflects the Mesopotamian belief in a connection between the earth and the heavens, serving both religious and administrative purposes within city-states.
