The then ruler and strongman of Gadwal called Peda Soma Bhupaludu (Somanadri) constructed this fort during 17th Century. To this day, the huge walls used for construction of the fort and the moats make Gadwal Fort really strong and impregnable.
Today after three centuries, it remains intact. The fort precincts are home to deity Sri Chennakesava Swamy Temple, Sri Ramalayam, Sri Venugopala Swamy temple, and a water body. The ruler Pedda Soma Bhupala had defeated the Nawab of Kurnool then and brought a 32-feet long Cannon as a symbol of victory, which is the biggest in India and is still seen in the fort. The government has taken many steps to restore the heritage of Gadwal fort. It is located near Gadwal town, between Hyderabad and Kurnool at a distance of 16 km from Erravelli Junction on Bangalore-Hyderabad NH 7.
