The central shrine, of the presiding deity Parimala Ranganathar, is made of green stone. The deity is seen in a reclining posture, facing east. The consort of Parimala Ranganathar is Parimala Ranganayaki, who is also called Chandrasaapa Vimochanavalli and Pundareekavalli. The sanctum houses the images of river gods Cauvery and Ganga, as well as that of Santhanagopalakrishnan. The Hindu god of creation, Brahma, is sculpted on the wall. The temple has shrines of Yoga Narasimhar, Rama, Anjaneya, Surya and Chandra. This temple has three prakarams (precincts) that house all the shrines and has a five-tier, east-facing Rajagopuram. The Dwajasthamba Mandapam and Garuda Mandapam have sculpted pillars, with the latter having images of ten avatars of Vishnu.
