Gulbarga Fort, Monument of National Importance and fortification in Kalaburagi, Karnataka, India.

Gulbarga Fort covers about 57 acres within a 3-kilometre perimeter of double walls and a 30-foot moat. Its 15 towers mounted 26 guns, each 8 metres long and still preserved. The photograph shows a dark stone wall with a pointed archway, rounded battlements and a metal gate.

The fort originated under local rule and was later enlarged by Al-ud-din Hasan Bahmani following his kingdom's separation from the Delhi Sultanate. This expansion brought substantial structural changes and new defensive features to the complex.

The Jama Masjid within the fort displays Persian architectural style with domes and arched columns reflecting Islamic influence. Visitors can observe this sacred space and the craftsmanship visible in its interior design.

The fort lies on plateau land in northeastern Karnataka, about 225 km from Hyderabad and 610 km from Bangalore by national highway; Kalaburagi Airport is the nearest. The walled area covers roughly 57 acres within a 3 km perimeter, so allow time to walk between the archway, citadel and Jama Masjid. Summers reach 45 °C and rain falls on only about 46 days a year, so mornings are easier going.

The fort's 15 towers once mounted 26 guns; each cannon inside is 8 metres long and still preserved. The Bara Gazi Toph, cast from five metal alloys, is counted among the longest cannons ever made.
