BAIBURT, a town of Asiatic Turkey, on the direct carriage road from Trebizond to Erzerum, situated on both banks of the Churuk river, which here traverses an open cultivated plateau (altitude, 5100 ft.), before turning east. It is the chief place of a kaza under Erzerum; the bazaar is poor, and there is no special industry in the town. The houses run up the hillsides on both banks of the river to a considerable height. On an isolated mass of rock, on the left bank, is the old castle, with extensive walls partly ruined, built originally by the Armenians and restored by the Seljuks. The principal gate with some Arabic inscriptions stands at the S.W. corner. There are remains of a vaulted chamber, a Christian church, a mosque and two covered staircases to the river. A fine view is seen from the summit over the plain and the Pontic ranges to the north. The population numbers 10,000, mostly Turkish with some Armenians. The place was occupied by the Russians under General Paskevich during their invasion of 1829, and was the farthest point westward then reached by them. (F. R. M.)
