The ancient civilization known for its ziggurats is Mesopotamia, particularly the Sumerians. Ziggurats are massive, terraced structures that served as temples for worship and religious ceremonies. Built using mud bricks, these architectural marvels were often dedicated to particular deities. The most famous ziggurat is the Great Ziggurat of Ur, which offered a blend of religious, administrative, and ceremonial functions. Mesopotamia, often referred to as the "Cradle of Civilization," made significant innovations in writing, law, and city planning, influencing subsequent cultures in the region and beyond.
