The Solah Khamba Masjid, or the sixteen-pillared mosque is one of the largest mosques in the country and the oldest surviving building in Bidar. Built in 1423-24 AD by Qubil Sultani, during the viceroyalty of Prince Muhammad, this mosque boasts massive columns, domes and arches. The architecture allows for plenty of fresh air and light. The landscape is open and spacious to accommodate the swarming numbers, who would come here during Friday prayers and important religious state functions. This mosque is also called Zanana Masjid as it is located near the Zanana enclosure. Other attractions nearby include the Gagan Mahal, Diwan-e-Aam, Takhat Mahal, Royal pavilion, Hazar kothari and Naubat khana. Jama Masjid and Kali Masjid are two other monuments nearby that should not be missed.
