Kodiakkarai also called Point Calimere or Cape Calimere, is a low headland of the Coromandel Coast, in the Nagapattinam district of the Indian state of Tamil Nadu. The Cape is located about 9 kilometres (5.6 mi) south of Vedaranyam in the delta region of the Cauvery River, and marks a nearly right-angle turn in the coastline. The antiquity of the area is evidenced by the Kodi Kuzhagar temple built during the Chola period, and a Chola lighthouse, which was destroyed in the 2004 Indian Ocean tsunami.

Vedaranyam is a town in Nagapattinam district in the Indian state of Tamil Nadu. The town is named after the presiding deity of the Vedaranyeswarar Temple. The recorded history of Vedaranyam is known from medieval Chola period of the 9th century and has been ruled, at different times, by the Medieval Cholas, Later Cholas, Later Pandyas, Vijayanagar Empire and the British. During India's independence struggle, C. Rajagopalachari, who would later become independent India's first Governor-General, launched a salt march in Vedaranyam parallel to the Dandi March launched by Gandhi in 1930 to protest against the sales tax levied on salt extraction.
