It is not known by whom and when the mosque located in the Inner Castle was built. Considering the similar features with the Artuqid mosques, it is thought to be an Artuqid work. It is thought that the mosque, located at the highest point of the castle, was built on the Roman Period temple. The structure, which was damaged during the Mongol invasion, was overhauled several times during the Ayyubid and Ottoman periods. There are inscriptions on the minaret giving the date 1325 and on the iwan and minbar the date 1396.

The harim, located in the south of a wide courtyard of the mosque, is entered through a deep iwan supported by stepped arches. The building, which developed in a transverse rectangular plan, has a single nave. Some sections and architectural elements were added during the repairs in the Ayyubid and Ottoman periods, and the plaster and decorations of the building were also renewed. The minaret is located to the west of the iwan that provides the entrance to the harem. The pedestal of the mosque, which exceeds the body wall, has a square plan. The body has the appearance of a truncated cone narrowing upwards, and it is ruined after a short part. It was built with rubble stone material.
