The ancient civilization famous for its ziggurats is the Sumerians. Ziggurats were massive, tiered structures built in ancient Mesopotamia, primarily serving as centers of worship and administration. These monumental buildings often had a temple at the summit, dedicated to the patron god of the city. The Sumerians, considered one of the earliest civilizations in human history, flourished in the region that is now modern-day Iraq and invented one of the first writing systems, cuneiform. The construction of ziggurats exemplifies their architectural skills and religious devotion, marking their legacy in human history.
