Kolanjiappar temple in Manavalanallur, a village on the outskirts of Virudhachalam in Cuddalore district in the South Indian state of Tamil Nadu, is dedicated to the Hindu god Murugan.

The temple is maintained and administered by the Hindu Religious and Endowment Board of the Government of Tamil Nadu.

As per Hindu legend, Sundarar, the famous Nayanmar saint in Saivite tradition belonging to the 8th century, came to Virudhachalam (called Thirumudukundram) during his old age.

Understanding that it is a divine play, Sundarar returned to Virudhachalam temple and sang praise of Shiva again.

The temple rituals are performed four times a day: Kalasandhi at 8:00 a.m., Uchikala poojai at 12:00 p.m., Sayarakshai at 6:00 p.m., and Arthajama Pooja at 8:15 p.m. Each ritual has three steps: alangaram (decoration), neivethanam (food offering) and deepa aradanai (waving of lamps) for the presiding deities.

During Adi festival, hundreds of devotees carry pots of milk and Kavadi around the streets of the temple, which is followed by a feast attended by close to 5,000 people.

Offering money or object equals to one's weight, tonsuring, carrying milk pots and piercing body parts with Vel are all other common forms of worship.
