Kalyanasundareswarar Temple, Thiruvelvikudi
The pesiding deity is Kalyanasundareswarar and the consort is Parimala Sugantha Nayaki.
Hymns have been composed in praise of the temple by Sambandar and Sundarar in the Thevaram. Sundarar is believed to have bathed in the Agni theertham at this spot to cure himself. Thiruvelvikudi was also the place where Shiva granted half of his body to Parvathi making Thiruvelvikudi the birthplace of the Ardhanarisvara cult.
