Ruins of Ishan Monastery (Turkey)
The church is a domed cruciform structure. The dome over the central square bay rests on four free-standing piers, each having a diameter of about two-meters.
During the conversion of the church into a mosque, a wall (visible on the left side of this photo) was constructed between the west arm and the central bay, the south and west entrances were closed, a mihrab niche facing in the direction of Mecca was constructed within the closed southern entrance, and the northern annex was converted into a prayer hall.
