The Mavadi Pillaiyar temple is one of the oldest Hindu Kovils (temples) in Chavakachcheri as well as in the northern province of the country. That was a time when temples received Majestic acknowledgment and Mavadi Pillaiyar temple too received the same. Thousands of pilgrims around the world gather at the temple during its annual festival. The weeklong colorful festival includes the thear structure pulling and many thanam and religious special blessings and worship.
The festival falls during the months of July and August every year. The area is jam-packed with roadside shops with plenty of clothing, toys, and foodstuff.
On the final day of the festival called the theetham, pilgrims take a bath in the pond located within the Kovil compound believing that all their sins are washed out.
Regular daily poojas and special poojas are conducted during main Hindu festivals such as Deepavali, Tamil new year, Navarathri and Thiruvamba etc. The large pond next to the temple adds beauty and significance to this Kovil.
