The building known as the İstanbulluoğlu Mosque in Akdağmadeni, Yozgat, was built as a church and is now open for prayer as a mosque. It is cut stone, rectangular in plan, and stands within a courtyard.

The round-arched narthex at the entrance was later closed in and a room made on each side; it has three arches, with angular columns at the corners and round ones in the middle. The minaret was built on top of the bell tower on the south side, and it is entered from outside. The roof is gabled and tiled, with the eaves projecting slightly. Inside, the building has three aisles under a vaulted ceiling, and the rear wall carries an apse in three sections. The mosque is in the İstanbulluoğlu quarter of Akdağmadeni.
