Located in the Aşağı Kayabaşı neighborhood, the church with a basilica plan was made of basalt cut stone. The main prayer hall is divided into three naves with 8 symmetrical columns and the middle nave is larger than the side naves. On the west side, the stairs on the right side of the entrance lead to the balcony. To the east of the church, which has a rectangular plan in length, there is an apse with three iwans, one large in the middle and a smaller one on both sides. Geometric ornaments are seen on the ceiling in the shape of a saddle and inside the arches connecting the columns. The church is generally well-preserved inside and out. The church is accessed by stairs from the main road and is used as a mosque. The front and two sides have porticoes, and the cloisters are covered with barrel vaults and painted in yellow, blue, and brick colors. The door is in the shape of a cross and there is a Greek inscription dated 1835 on the entrance door. In addition, the decorations made on both sides and the upper part of the door are covered with whitewash today. It is popularly known as the Begum Mosque. It is generally well preserved, but there are spills on the ceiling and frescoes.
