He mentions that many Vedic scholars learnt and taught there.
This sacred place is one among the Pancha Krishna kshetrams. The Sthala Puranam (traditional story) of this place is that a king named Uparisaravasu had a chariot which was invincible. Since he refused to stop to worship at this temple while flying on his chariot over this temple with his queen, Garuda caused this chariot to fall into the temple tank. Perumal, as a cowherd boy helped him and the king repented his arrogance.
