The Thayumanavar Temple is a Hindu shrine dedicated to Lord Shiva, located within the Rockfort temple complex in the city of Tiruchirappalli, in Trichy district, Tamil Nadu. The temple, situated near the base of the Rockfort, was constructed by the Pallava king Mahendravarman I in the 6th century AD. The presiding deity is known by several names: Thayumanavar, Mathrubootheshwar, Thayumaneswarar, and Sevvanthi Nathar. The consort of Lord Shiva, the divine mother, is called Mattuvar Kuzhali or Sugandha Kundalambikai.
The Rockfort temple complex contains three significant shrines: two are dedicated to Lord Ganesha—one located at the foot of the rock and the other at the top, known as Ucchi Pillayar Temple. The Thayumanavar Temple, the largest of the three, is positioned between these two shrines.
The Rockfort itself is a massive fortress perched on a 273-foot-high rock, featuring a collection of monolithic rocks that house numerous rock-cut cave temples. Originally built by the Pallavas, the fortress was later reconstructed by the Madurai Nayaks and the Vijayanagara rulers. Some parts of the temple complex, particularly the major structures, are believed to have been built during the 8th century by the Pandya Empire. Geologists estimate that the rock formation dates back around 3.5 billion years. In ancient times, the region was known by various names such as Sirappalli, Rishabachalam, and Dhakshina Kailasam.
The temple has been praised in the Thevaram hymns by Thirugnana Sambandar, a 7th-century Tamil Saivite poet, who composed eleven verses dedicated to Thayumanavar in the First Thirumurai. His contemporary, Appar (Thirunavukkarasar), also composed ten verses in the Fifth Thirumurai, in praise of the deity. Since it is celebrated in the Thevaram, Thayumanavar Temple is classified as a Paadal Petra Sthalam, one of the 276 temples mentioned in the Saiva canon.
Additionally, the temple's deity Muthukumaraswamy is revered in the Thirupugazh hymns, composed by Arunagirinathar, a 15th-century saint. The Thayumanavar Temple is the 123rd Devaram Paadal Petra Shiva Sthalam, and the 6th Shiva Sthalam located on the southern bank of the River Cauvery in the Chola region.
