Perur Pateeswarar Temple is a temple dedicated to Shiva, The temple was built by Karikala Chola. The temple has been patronized by poets like Arunagirinathar and Kachiappa Munivar. Lord Shiva, known as ‘Patteeswarar’, is the presiding deity of this temple together with his consort Parvati, who is known as ‘Pachainayaki’. The deity is believed to be ‘Swayambu Lingam’ (self emerged). It is said a divine cow Kamadenu performed severe penance on Lord Shiva seeking the post of Lord Brahma to take up the creation work.  It was pouring its milk on the Shivalinga here hidden in an anthill.  Its calf Patti in a playful mood hit the anthill and demolished it.  Shocked Kamadenu fell at the feet of Lord and sought His pardon.  Appearing before the divine cow, Lord said that He was only pleased with the calf.  Lord further said that the place was the first among the salvation sthalas to His devotees and that He would grant the creation boon to Kamadenu at Tirukaruhavur and advised it to perform penance there.  Lord mercifully said that this place (Perur) would be praised as Kamadenupuram and Pattipuri after name of the calf and that He would stay in the place as Patteeswarar. The foot print scar of Kamadenu the divine cow is visible on the head of Shivalinga in the temple. There is a tamarind tree in front of the temple known as Piravapuli meaning that its seeds will not germinate wherever sown. There will be no worms in the cow dung in the surrounding area.
