a town of Asiatic Turkey, in the pashalik of Diarbekir, on a bold limestone crag of Mount Masius, about 2300 feet above the sea, 57 miles S.E. of Diarbekir, and 335 N.W. of Baghdad. The summit of the rock is occupied by the castle, and the town is built on the southern and eastern sides. The streets consist of terraces, running along the hill, and are joined to each other by flights of steps. The houses are built of stone, and are in general small, with flat roofs. The town possesses eight mosques, with some bazaars and public baths. The castle is now in ruins, but commands a magnificent view over a large extent of rich and well cultivated land. Linen and cotton fabrics are manufactured here, and a considerable trade is carried on in these and other articles. The population is estimated at about 20,000, two-thirds of whom are Mohammedans, and the remainder Christians with a few Jews.
