It is the most popular attraction of the city. The fort was built by the Kakatiya rulers in 1294 AD. The three sides of the fort are surrounded by double rows of massive low circuit walls, which are built on a hill 88m high. Its inner wall was constructed using big blocks of stones that are blocked together without any binding material between them.
The main attraction, however, is a 41 ft long stone slab. It carries records in Telugu with a scene whereby huge slabs are hauled up a hill with the help of buffalo carts.
One more reason for the fort being so popular is the stone inscriptions in Persian and Arabic language. These inscriptions are said to belong to Ali Burj. You can see ruins of ancient temples and several tanks on the premises.
