Devanahalli Fort is located 35 kilometers (22 mi) north of Bangalore city, at Devanahalli in the State of Karnataka, India. Chieftain Malla Byre Gowda of Avathi, a Vijayanagara empirevassal, built a mud fort in c. 1501 at Devanadoddi (now called Devanahalli). In the late 18th century, Hyder Ali re-constructed the fort in stone resulting in the current structure. The birthplace of Tipu Sultan, also known as Tiger of Mysore, is located near to the fort. The fort is situated on the side of National Highway 7, near the Bengaluru International Airport.
