The Varadharaja Perumal Temple or Hastagiri or Attiyuran is a Hindu temple dedicated to Lord Vishnu and is one of the Divya Desams, the 108 temples of Vishnu believed to have been visited by the 12 poet saints, or Alwars.

It was originally built by the Cholas in 1053 and was later expanded during the reigns of the great Chola kings Kulottunga Chola I and Vikrama Chola. In the 14th century another wall and a gopura was built by the later Chola kings.
