Bangalore Fort began in 1537 as a mud fort. The builder was Kempe Gowda I, a vassal of the Vijaynagar Empire and the founder of Bangalore. Hyder Ali in 1761 replaced the mud fort with a stone fort and it was further improved by his son Tipu Sultan in the late 18th century. It was damaged during an Anglo-Mysore war in 1791. It still remains a good example of 18th-century military fortification. The army of the British East India Company, led by Lord Cornwallis on 21 March 1791 captured the fort in the siege of Bangalore during the Third Mysore War (1790–1792). At the time the fort was a stronghold for Tipu Sultan. Today, the fort's Delhi gate, on Krishnarajendra Road, and two bastions are the primary remains of the fort. A marble plaque commemorates the spot where the British breached fort's wall, leading to its capture. The old fort area also includes Tipu Sultan's Summer Palace, and his armoury. The fort has provided the setting for the treasure hunt in the book Riddle of the Seventh Stone.

Kempe Gowda I locally venerated as Nadaprabhu Kempe Gowda, or commonly known as Kempe Gowda, was a governor under the Vijayanagara Empire in early-modern India. He is famous for the development of Bangalore Town in the 16th century. Kempegowda erected many Kannada inscriptions across the region. He also authored Ganga-gauri-vilasa, a yakshagana (verse-play) in Telugu. He is commemorated with various statues and memorials and many places are named after him in Bangalore.
