Kailasanathar Temple is the temple of the Lord of Mt.Kailash dedicated to Lord Siva. The temple was built during 685-705AD. It is the first structural temple built in South India by Narasimhavarman II (Rajasimha), and who is also known as Rajasimha Pallaveswaram. His son, Mahendravarman III, completed the front facade and the gopuram (tower). Prior temples were either built of wood or hewn into rock faces in caves or on boulders, as seen in Mahabalipuram. The Kailasanathar temple became the trend setter for other similar temples in South India. According to local belief, the temple was a safe sanctuary for the rulers of the kingdom during wars. A secret tunnel, built by the kings, was used as an escape route and is still visible. It is believed, by visiting this temple, devotees get rid of the ill effects of Planet Ketu. The outstanding feature of sculptures is the profusion of a depiction of the erect lions projecting out in several directions. There are two sculptures of Shiva here which are seen holding the Veena (musical string instrument) in the hand. There is a lot of difference between the Veena found in the said sculptures and the present day Veena. There are also beautiful sculptures of Mathahvialasa Prakshanam. The temple also has the earliest stone inscription records of the twenty-eight Saivagamas (Shaiva saints) in which the Pallava King Rajasimhavarman states his faith in Shaivism.
