Nusaybin

Nusaybin, the ancient Nisibis, lies on the Jaghjagh River, the old Mygdonius, at the foot of the Mount Izla escarpment on the southern edge of the Tur Abdin hills. In late antiquity it was a bulwark of the Roman East against Persia and the seat of a famous school of the Church of the East. The Mongols overran it in the 13th century, and it then passed to the Aq Qoyunlu, the Kara Koyunlu and the Safavids until the Ottomans took it in 1515.
