With an annual figure of 1.000.000 visitors the Pergamon Museum ranks among the most popular buildings of the state museums. Visitors can experience the antiquity through the reconstructions of momentous archaeological construction ensembles. Entering the market Gate of Miletus, an outstanding piece of Roman architecture, the visitors reach the Ishtar-Gate with its Prozessionsstrasse of Babylon in the Vorderasiatisches Museum (Museum of the Ancient Near East). The richly ornamented Mschatta-Facade of a Jordanian desert-residence can be found in the Museum für Islamische Kunst (Museum of Islamic Art) on the first floor. The Hall of Hellenistic architecture and the Hall containing the Pergamon Altar are under reconstruction.
