This is one of the oldest temples in south India and belongs to the latter half of the 7th century AD, built with granite blocks. As it is on the shore overlooking the Bay of Bengal it is called as the Shore Temples. Said to have been constructed by King Rajasimha, it is a good example of the first phase of structural temples constructed in the Dravidian style of architecture. This was a busy port during the reign of Narasimhavarman II. It has two shrines dedicated to Vishnu and Shiva, facing the east and the west. This temple’s architecture influenced that of the Cholas who succeeded the Pallavas as the dominant dynasty in the area now covered by Tamil Nadu.
