The temple occupies an area of around . The central shrine houses the image of Vilwanatheswarar in the form of Lingam facing east. Unlike other temples, where the Nandi is located axial to and facing the sanctum, in this temple the Nandi faces the opposite direction. The sanctum is structured in the form of a moat. The central shrine is approached through the flagstaff and Mahamandapam, both which are located axial to the gateway. The shrine of Valambigai, the consort of Shiva facing West is located in the Mahamandapam leading to the sanctum. As in other Shiva temples in Tamil Nadu, the shrines of Vinayaka, Murugan, Navagraha, Chandikesa and Durga are located around the precinct of the main shrine. There is a hall of Nataraja near the sanctum. The image of Vinayagar is sculpted on a square base and a Padma peeta and sported holding a mango in his trunk. The Dvarapalas on both sides on the entrance of the sanctum are of architectural importance. One of them is unique and is sported in dance posture with a raised hand. There is a shrine of Pathaleswarar in the first precinct where the shrine of Lingam is located underground. In modern times, the temple is maintained and administered by the Hindu Religious and Charitable Endowments Department of the Government of Tamil Nadu.
