25 km from Trichy, this temple is on a 50 feet tall hill of white rock; hence this was called as ThiruVellaiParai (white rock). A Yogi named Pundarikakshan used to offer Tulsi(Holy Basil) every day from his Nandavanam to the God and Goddess in the temple. Pleased by the Yogi's bhakti, Perumal blessed him. Perumal is also called as Pundarikakshan. Tirumangai Azhwar sang hymns on Pundarikakshan here.
