It was built in the 10th century on an isolated monolithic rock by the western Chalukya ruler Tribhuvanamalla Vikramaditya VI and was thus named after him as Tribhuvanagiri.
At the foot of the fortified rocks 609.6 meters above the sea level stands the town of Bhongir, it has a unique egg-shaped construction with two entry points protected by huge rocks, so the fort was considered practically impregnable by invading armies. The splendid historical fort with the awe-inspiring rock and the aesthetically fortified courts which have stood the ravages of time stir the imagination of tourists.
A moat that encircles the fort, a vast underground chamber, trap doors, an armoury, stables, ponds, wells etc., can make interesting viewing. The view from the top of the surrounding countryside can be impressive. The Bala Hisar or citadel on the top of the hill gives a bird’s eye view of the neighbouring area. The fort is associated with the rule of queen Rudramadevi and her grandson Prataparudra.
