As per Hindu legend, Shiva is believed to have destroyed eight different demons namely Andakasuran, Gajasuran, Jalandasuran, Thirupuradhi, Kaman, Arjunan, Dakshan and Taaragasuran. There are Ashta Veeratanam temples built signifying each of his victories in the war,[6] and also as places where he is believed to have performed with fury.
The eight temples are: Tiruvadigai Veerattaaneswarar Temple at Thiruvadigai, Tirukkovilur Veerateshwarar Temple at Tirukoilur, Veerateswarar temple at Korukkai or Thirukkurukkai, Amirtagateswarar Temple at Thirukadaiyur, Vazhuvur Verateswarar Temple at Vazhuvoor, Keelaparasalur Veerateswarar Temple at Tirupariyalur, Kandeeswarar Temple at Thirukkandiyur and Tiruvirkudi Veerataneswarar Temple at Thiruvirkudi. Shiva in all these temples are described to have used bow and arrow, trident and spear.
It is one of the shrines of the 275 Paadal Petra Sthalams - Shiva Sthalams glorified in the early medieval Tevaram poems by Tamil Saivite Nayanar Tirunavukkarasar. The twelve songs of Appar are compiled in fourth Thirumurai as 49th and 50th canto. The thirty-one songs of Appar are compiled in the fourth Thirumrai ten each under 31st and 107th canto, while the remaining eleven in fifth Thirumrai under 11th canto. The ten songs of Sundarar are compiled in seventh Thirumurai in 28th cantor.

Tirunavukkarasar describes the feature of the deity as:
காப்பதோர் வில்லு மம்புங் கையதோ ரிறைச்சிப் பாரம்
தோற்பெருஞ் செருப்புத் தொட்டுத் தூயவாய்க் கலச மாட்டித்
தீப்பெருங் கண்கள் செய்ய குருதிநீ ரொழுகத் தன்கண்
கோப்பதும் பற்றிக் கொண்டார் குறுக்கைவீ ரட்ட னாரே.
The presiding deity is worshipped by devotees praying for mental and well-being.
The temple priests perform the pooja (rituals) during festivals and on a daily basis. Like other Shiva temples of Tamil Nadu, the priests belong to the Shaivaite community, a Brahmin sub-caste.
The temple rituals are performed four times a day; Kalasanthi at 7:00 a.m., Uchikalam at 10:00 a.m., Sayarakshai at 6:00 p.m. and Ardha Jamam at 8:30 p.m. Each ritual comprises four steps: abhisheka (sacred bath), alangaram (decoration), neivethanam (food offering) and deepa aradanai (waving of lamps) for both Veerateeswarar and Gnanambigai.
The worship is held amidst music with nagaswaram (pipe instrument) and tavil (percussion instrument), religious instructions in the Vedas read by priests and prostration by worshippers in front of the temple mast. There are weekly rituals like somavaram and sukravaram, fortnightly rituals like pradosham and monthly festivals like amavasai (new moon day), kiruthigai, pournami (full moon day) and sathurthi.
There is a temple procession during the Tamil month of Margazhi (December- January) Thiruvadhirai festival. Kamadhahana festival during Masimagam during (February - March) followed by 10-day Brahmostavam are the major festivals in the temple.
