Tucked into the eastern edge of the bazaar neighborhood is the Ulu Camii, built in the 11th century by the Artuqid Dynasty.
The building suffered badly during a Kurdish uprising in 1832 and has been partially restored. Beneath a prism-shaped dome supported by pillars lies a prayer room divided into three sections. The minaret, with its unique stone carvings, is the highlight of a visit here.
The surrounding bazaar neighborhood is a great area to soak up the modern bustle of this ancient town, so be sure to have a wander through the narrow alleyways before or after visiting the mosque.
