According to the legend, a Saint called Pundarika Muni had a vision of Lord Vishnu as Anantasayi (Lord Vishnu in reclining posture) at this spot. Accordingly, the temple has the idol of Lord Vishnu in a reclining posture, facing east.
The original temple is built by the Pallavas. The temple had a major renovation in the 19th Century AD.
The ancient Hindu temple is very near the famous Mamallapuram seashore temple at Mahabalipuram, about 105 kilometers from Chennai.
