Susa Castle

Susa(Shush-in South West Iran) is one of the oldest cities in the world. Excavations have established that people were living at the so-called acropolis in 5000 BCE and have shown the existence of urban structures about 4000, and it is reasonable that the town, situated on a strip of land between the rivers Karkheh (Choaspes) and Dez (Eulaeus), was already the political center of Elam in the fourth millennium. The ruins of a castle on a steep hilltop date back to this period. It has partly been overbuilt with a modern castle that was used by the French archaeologists.
