Kara Davut Pasha Mosque, Üsküdar

"Kara Davut Pasha Camii is a little-known mosque in Üsküdar, probably built at the very beginning of Beyazit's reign. It is a very curious mosque, perhaps unique in form at least in Istanbul, and seems to have escaped mention in modern times." ¹

'A square central area is covered by a large dome on a high windowless octagonal drum; to left and right are square areas of the same size, each under a dome of equal diameter but considerably lower. Wide, heavy arches slightly divide the room into three parts and support the three domes, producing a wide, shallow prayer room three times as broad as deep — a variant of the cross-axial multi-unit type not met with elsewhere.' ¹
