Market Gate of Miletus – Pergamon Museum – http://bit.ly/1kebVCD
The other two photos here are the Pergamon altar and the Ishtar Gate into Babylon
It is hard to describe the Pergamom Museum for it is unlike most museums that I have visited in that much of its contents are large pieces of ancient buildings which have been rebuilt inside the walls of the museum, and in fact the museum has been designed to house some of these large buildings.
