There is a temple dedicated to Sri Kurmanatha, which is the second avatar of Lord Vishnu, Kurma Avatar (Tortoise). This is the only temple of Kurmanatha in India. There is also a Yoganandha Narasimhan temple in front of Sri Kurmam temple. Simhachalam Devasthanam took the responsibility for the temple improvement. The moolasthanam (central piece) is considered to be large saligrama. The Kurma (Turtle) is known as Sri Kurmam in the 'Sampradayam'. The image is not a sculpture crafted by man, but the fossil of an actual (large-size) turtle. The head of the deity is in the form of a Kurma (tortoise) and is represented by a Vishnu namam, the tail being represented by a Saligrama presented by Adi Sankaracharya.
The artistic beauty of the temple lies in the carvings of Vishnu and other deity statues in a glorious way of architecture. There is a mandapam in front of the temple on Lion pillars. One unique feature of this temple is that it has Dhwajastambams in the front and back of the temple. That is because the deity faces the back of the temple on the west.
