Tirupperunthurai (also called the Athmanathaswamy temple) is located in Avudaiyarkoil village, near Aranthangi in the Pudukkottai district of Tamil Nadu. It was built to honor Lord Shiva. One of the sacred books of Tamil Saiva Siddhanta, Manikkavasagar's Tiruvasakam, originated from this shrine. Manikkavasagar is said to have converted the king to follow Shiva, and built the temple with money that had been intended for war-horses.
