Thirumayam: (25 kms.) This place has been celebrated in a song by Tirumangai Mannan, one of the Alwars. It lies at the foot of a hill crowned by an old fort. Nearby is Adirangam, a place which became popular even earlier than Srirangam itself. It contains a rock temple with twin shrines of Shiva and Vishnu. Built in the 7th Century, the monuments contain characteristic features of the early Pallava cave temples of Mamallapuram. Some of the inscriptions here contain musical notation.
