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.
