It is located 22 km from Tirunelveli. Constructed in the Tamil style of architecture, the temple is glorified in the Nalayira Divya Prabandham, the early medieval Tamil canon of the Alvar saints from the 6th–9th centuries CE. It is one of the 108 Divya Desams dedicated to Vishnu, who is worshipped as Vaikunthanathar and his consort Lakshmi as Vaikunthavalli. The temple is also classified as a Nava Tirupati, the nine temples revered by Nammalvar located in the banks of Tamiraparani river. The temple is next only to Alwarthirunagari Temple in terms of importance among the nine Navatirupathi temple. The temple is one of the Navagraha temples in Vaishnavism, associated with Surya, the sun god.
A granite wall surrounds the temple, enclosing all its shrines and two of its three bodies of water. The rajagopuram, the temple's gateway tower, is 110 ft (34 m) tall. Thiruvengadamudayan hall houses rare life size sculptures commissioned during the 16th century.
