At a distance of 23 km from Karaikal, Thirukkadaiyur is a popular temple town located on the east coast of Tamil Nadu in the Nagapattinam district. The Amritaghateswarar - Abirami Temple, dedicated to Lord Shiva is the most famous temple in Thirukkadaiyur.
The presiding deity of this temple is Sri Amirthalingeswara and his consort is Sri Abirami. Thirukkadaiyur is one of the 8 Veera Sthalas, where Yama was clashed with Lord Shiva. It is believed that this is the place where Lord Shiva protected Markandeya, son of Mrikandu, from Yama. The scar caused by the Yama's rope is visible on the Linga during abisheka times.
