The Bahmani Sultanate in the Deccan broke away from the Tughlaqs in 1347, and ruled from Gulbarga, Karnataka and then Bidar until overrun by the Mughals in 1527. The main mosque (1367) in the large Gulbarga Fort or citadel is unusual in having no courtyard. There are a total of 75 domes, all small and shallow and small except for a large one above the "mihrab" and four lesser ones at the corners. The large interior has a central hypostyle space, and wide aisles with "transverse" arches springing from unusually low down (illustrated). This distinctive feature is found in other Bahmanid buildings, and probably reflects Iranian influence, which is seen in other features such as a four-iwan plan and glazed tiles, some actually imported from Iran, used elsewhere. The architect of the mosque is said to have been Persian.
