On its southern/eastern side is the prayer hall, featuring two transverse naves formed by rows of five horseshoe arches parallel to the qibla wall (i.e. the wall towards which prayers face).[7] The mihrab, a decorative alcove or niche in the qibla wall that symbolizes the direction of prayer, is a small octagonal space topped by a dome of muqarnas. On either side of the mihrab are two small doors leading to other rooms.
