From 900BC onwards came waves of invasions from Assyrians, Persians, and Macedonians until the Greco-Iranian Commagene kingdom was founded in 69BC. This was the civilisation that built the statues on top of nearby Mount Nemrut. The capital was in Samsat (Samosata) but the town of Adıyaman was a walled city of the Commagenes. The city walls of Adıyaman have been restored and replaced many times since.
