The Sri Vaikuntanatha Swamy Temple is a 500-year-old Vaishnavite temple located in the village of Therani in the Chittoor district of Andhra Pradesh. The temple is dedicated to Lord Vishnu, who is known as Vaikuntanatha. The temples were built during the 16th century on the banks of the Kushasthali River. The temple is 5 km from the city of Nagari and 50 km from the city of Tirupati.
The temple was built during the 16th century by Sudarsanachary, an expert in the royal court of Karvetinagaram, which was part of the Vijayanagara Empire. The temple was very neglected and became a dilapidated structure over a period of time. The temple had undergone recent renovation work with donations from a devotee.
