Southeast Anatolia
Situation and characteristics
Adiyaman, capital of the province of that name, is situated within the plateau region of southeast Turkey, to the south of the east Taurus mountains. It lies on the western edge of a flat depression, the southeast limit of which is
formed by the Euphrates. Although the town, the center of an agricultural area (cotton, apricots, pistachios), has little worth seeing, it makes an excellent base from which to explore the historic Kommagene sites.
Prior to the creation of the Turkish Republic Adiyaman was known as Hisn Mansur (Mansur's Castle), having begun life in 758 as a fortress (thugur) against the Byzantines. It was built under Caliph Marwan by the Omayyad leader Mansur Ben Ga'wana in succession to the earlier Roman town of Perre.
