Thanthoneeswarar temple complex has a single prakaram (outer courtyard) and a two-tiered vimana (tower over the sanctum). The central shrine faces east and holds the image of Thanthoneeswarar (Shiva) in the form of lingam made of granite. The granite images of the deities Ganesha (son of Shiva and god of wisdom), Murugan (son of Shiva and god of war), Nandi (the bull and vehicle of Shiva) and Navagraha (nine planetary deities) are located in the hall leading to the sanctum. As in other Shiva temples of Tamil Nadu, the first precinct or the walls around the sanctum of Thanthoneeswarar has images of Dakshinamurthy (Shiva as the Teacher), Durga (warrior-goddess) and Chandikeswarar (a saint and devotee of Shiva). The shrine of Kunkumavalli, the consort of Thanthoneeswarar, faces North and is depicted with Ankusam and lotus in her two hands. The temple precinct is surrounded by granite walls.
