The Sri Varadaraja Perumal Temple in Kodavasal was built in the late 9th century by the Chola Kings. After centuries of plunder, and then disuse, the temple got a lease of life when the Swami Dayananda Educational Trust took over its administration in 2006.

The revival of the Vedic traditions has not just renewed the sanctity of the temple; it has also spawned a micro-economy of traders and service providers around it: flower makers, musicians, weavers, ornament makers, etc. The temple, which follows the Vaikhasana Agama, also provides the students of the veda patashala valuable experience on temple worship procedures.

At the temple, you can find idols of Sridevi, Bhoomidevi Samedha, Sri Varadaraja Perumal, Sri Narasimhar and Sri Anjaneyar. The temple celebrates festivals like the Brahmotsavam, Pavithrothsavam, Krishna Jayanthi, Purattasi Saturdays Special Darshan, Karthigai Deepam, Vaikunda Ekadasi, Margazhi Koodarai Valli, Thai Pongal, Thai Amavasya Garuda Sevai, Akshayathrithiya and Vijayadasami.
