The Oppiliappan Temple at Thirunageswaram, about 5 km north of Tiruvarur, is one of the 108 Divya Desams — the sacred Vaishnava pilgrimage sites celebrated in the devotional hymns of the Alvars. The presiding deity, Oppiliappan (a form of Vishnu), sits with his consort Komalavalli in a temple renowned for the fine quality of its sculpted panels and its unusual ritual custom of preparing offerings without salt.
The gopuram and outer corridors contain well-preserved sculpture, and the atmosphere in the inner sanctum during puja is particularly concentrated and devotional. The temple is active and well-maintained. It is easily visited in combination with the great Thyagaraja Temple in Tiruvarur town — the two are connected by a direct road through paddy fields and make a natural pairing for a morning of temple visiting.
