History 
The modern town of Kalavai, in Kalavai taluk of Ranipet district, Tamil Nadu, situated about 100 km from Madras, is a village of historic importance from the time of the Pallavas since the 8th century AD. Ancient relics and inscriptions relating to the village are found in the local Siva temple named Thirukkaraesvara Temple. Probably the temple was built by one Thirukkarai and hence the name Thirukkaraesvara (an analogy with Rajarajeshvara). If so the history of the village could be traced to the Sangam age. The area was under the control of the Malaiyamāns of Thirukkoiyilur where ruled the famous chieftain Malaiyamān Thiru-mudikkārai who has been sung by eminent Sangam poets like Avvaiyar, Paranar, and Kapilar. It is not unlikely that Thirukkarai of this family built the Siva temple after whom it came to be called Thirukatisvaram. The Sthala purāna of the village seems to support this antiquity. Its close link to Malaiyanur may be seen in the sequence. There is also Angalaparameshwari Amman Temple, which is more than 100 years old and is very famous in the southern Indian states like Andhra Pradesh, Karnataka and Kerala. People are seen regularly visiting the temple to recover from black magic effects. Climate
