People look to a reconstructed head of a Sumerian woman during a media preview of the exhibition ' Uruk 5,000 Years of the Megacity' at the Pergamon Museum Berlin, Wednesday, April 24, 2013. Berlin’s Pergamon Museum is offering visitors a glimpse of perhaps the world’s first real metropolis in a new exhibition that traces the long history of Uruk, in present-day Iraq. The show marks a century of excavations at Uruk. But even now, organizers say that only about 4.5 percent of the sprawling site in the Iraqi desert has been explored.
