The temple has a three-tiered gopuram, the gateway tower and all the shrines of the temple are enclosed in concentric rectangular granite walls. The central shrine is approached through the gateway tower, a flag post, a mukha mandapa and an Ardha mandapa, all of which are axial to the sanctum. The central shrine houses the image of Marundeeswarar in the form of Lingam. The shrine of Irulneeki Thayar (also called Anthaga Nivarini), facing West is located in a shrine behind sanctum. The central shrine is approached through a Mahamandapam and Arthamandapam. As in other Shiva temples in Tamil Nadu, the shrines of Vinayaka, Murugan, Navagraha, Chandekeswara and Durga are located around the precinct of the main shrine. There is a shrine of Agastheeswarar in the second precinct in the southeastern direction. The shrine of Gnanambigai is on the South Western corner of the temple facing East.
