Mahabalipuram, derived from 'Mamallapuram'(Tamil) is the prior and colloquial name of a town in Kancheepuram district in the Indian state of Tamil Nadu, now officially called Mamallapuram. It has an average elevation of 12 metres (39 feet). Mahabalipuram was a 7th century port city of the South Indian dynasty of the Pallavas around 60 km south from the city of Chennai in Tamil Nadu. The name Mamallapuram is believed to have been given after the Pallava king Narasimhavarman I, who took on the epithet Mahamalla (great wrestler), as the favourite sport of the Pallavas was wrestling. It has various historic monuments built largely between the 7th and the 9th centuries, and has been classified as a UNESCO World Heritage Site.
