Ziggurat of Ur
Location: Iraq.
Built: 21st century B.C. The Ziggurat of Ur was built by King Ur-Nammu and dedicated to the god Nanna. Today only the foundations remain, and part of the structure, including the staircase and lower façade, was rebuilt by Saddam Hussein in the 1980s. It has been closed to the public since 2003, although U.S. military personnel have been able to access the site thanks to its proximity to the Tallil Air Base.
