The Gulbarga Fort (kn: ಗುಲ್ಬರ್ಗ located in Gulbarga City in the Gulbarga district of North Karnataka, India was originally built by Raja Gulchand during the Warangal dynastic rule. It was subsequently significantly enlarged in 1347 by Al-ud-din Bahmani of the Bahmani Dynasty after he cut off his ties with the Delhi Sultanate; Islamic monuments such as mosques, palaces, tombs, and other structures were also built later within the refurbished fort. The Jama Masjid built later, within the fort, in 1367, is a unique structure built in Persian architectural style, fully enclosed, with elegant domes and arched columns, which is unlike any other mosque in India.
