The ziggurat is also cited as Ur-Nammu Ziggurat for its builder Ur-Nammu. An example of a simple ziggurat is the White Temple of Uruk, in ancient Sumer. The top of the ziggurat was flat, unlike many pyramids. The height is speculative, as only the foundations of the Sumerian ziggurat have survived. He built the monument known as the Great Ziggurat, and an associated temple. The ziggurat itself is the base on which the White Temple is set. It was designed according to ancient ziggurat mound proportions used in votive worship. Ur's most prominent temple is the Great Ziggurat, which can be seen today. Another important site is Tepe Sialk, where the only remaining Proto-Elamite ziggurat is still seen. The Great Ziggurat itself has far more graffiti, mostly lightly carved into the bricks. ISIL destroyed a 3,000-year-old Ziggurat. The outer layers of the ziggurat are made from fired bricks. Duke Red takes Tima away to the Ziggurat. The remains of the ziggurat were first discovered by William Loftus in 1850. Proposed reconstruction of the Hanging Gardens and the great ziggurat never took place.
