Temple Layout - This Shiva temple, located on the southern bank of the river 'uppanaru', is characterized by its modest entrance without a 'gopuram' and adjacent to the temple is 'Chandra Theertham', providing a serene setting. Upon crossing the threshold, visitors are greeted by the nandi mandap. Surprisingly, there is no dwajasthambam here. As one navigates through the prakaram, the sight of Parashara Maharishi worshipping a Shiva Linga captures our attention. Moving towards the western side of the prakaram, one encounters sannidhis dedicated to various deities such as Vinayaka, Subrahmanya with Valli-Devianai, Vilva Nathar, Akilandeswari, and Mahalakshmi. Placed next are a pantheon of idols; Bhairavar, Saneeswarar, Vinayaka, Kailasa Nathar, and Bhadra Kaali, all lined up one after the other.

After completing the walk around the prakaram and proceeding further inside the temple, one can see the 'Swayambhu Linga' of the presiding deity Sundareshwarar, placed on a square 'peetam', accompanied by a relatively small-sized 'baanam' in an east-facing sannidhi. As we stand before the sannidhi facing the deity, to the right is the south-facing sannidhi of the female deity. The divine idol of Goddess Sundarambal is believed to have been discovered from the depths of the ocean. During 'Theertha vaari', a ritual that involves taking deities for a sacred bath, It is customary in shiva temples to take the deity's idol to a river or a ocean. where as here, it is the Goddess Who is taken to the sea on the full moon day falling in the Tamil month of Maasi.
