The Temple of Hadrian, Ephesus, Turkey. The Temple of Hadrian dates from the 2nd century but underwent repairs in the 4th century and has been re-erected from the surviving architectural fragments. The reliefs in the upper sections are casts, the originals being now exhibited in the Selcuk Archaeological Museum. A number of figures are depicted in the reliefs, including the emperor Theodosius I with his wife and eldest son. Ephesus was once the most important commercial centre of the ancient world and also a religious centre for early Christians. It was one of the twelve cities of the Ionian League during the Classical Greek period.
