Rayadurg Fort is located at Rayadurg in Anantapur District
. The fort belonged to the Vijayanagar Empire
and the inscriptions on the walls of the fort gives evidence to this fact.
The Rassasiddula Temple, which stands within the fort, is built of a single stone. The temple is embellished with sculptures of Jain gurus and their disciples. Narasimha Swamy Temple, Rama Temple, Neelakanteswara Swamy Temple, and Jambukeshswara Temple are shrines nearby.
