Probably built during the reign of Alā ad-Dīn Kayqubād ibn Kaykhusraw, the mosque has a rectangular plan running in an east-west direction. The interior of the building is divided into six sections with spolia of Roman Imperial columns, and each section is covered with a dome. Considering its independent minaret, the location and condition of its mihrab, and the vaulted section to the west, some scholars suggest that the mosque’s construction predates the Seljuk Period or it was converted from a church.

The building has two doors, one on the north and the other on the east. The east door has a depressed arch and is currently used as the main entrance. On the east façade, daylight comes in from the windows with iron bars at the door level and above, to the south of the door. There is a renovation inscription dated 1373 above the window over the door and in a frame with a pointed arch in the niche between the door. The north and south façades of the building have barred windows, which are rectangular below and round-arched above. There are no windows on the west façade.

The east-west-oriented prayer hall is divided into six square sections with 12 columns of different thicknesses and topped with Corinthian and Doric capitals. These sections are covered with domes featuring Turkish triangles. The vaulted section to the west of the place of worship is inconsistent with the general plan. The mihrab on the south wall gives the impression that it was added later. The semicircular mihrab niche is at a 30-degree angle to a wall that does not face the kiblah. The building might not have been decorated, but some glazed tile and plaster fragments were found during its repair.
