Mamallapuram, also known as Mahabalipuram, is a town in Chengalpattu district in the southeastern Indian state of Tamil Nadu, best known for the UNESCO World Heritage Site of 7th- and 8th-century Hindu Group of Monuments at Mahabalipuram. It is one of the famous tourist sites in India. The ancient name of the place is Thirukadalmallai. Mamallapuram was one of two major port cities in the Pallava kingdom. The town was named after Pallava king Narasimhavarman I, who was also known as Mamalla. Along with economic prosperity, it became the site of a group of royal monuments, many carved out of the living rock. These are dated to the 7th and 8th centuries: rathas (temples in the form of chariots), mandapas (cave sanctuaries), the giant open-air rock relief the Descent of the Ganges, and the Shore Temple dedicated to Shiva. The contemporary town plan was established by the British Raj in 1827. Etymology The earliest mention of the city is found in the 1st century work called Periplus of the Erythraean Sea by an unknown Greek navigator. Ptolemy, the Greek geographer refers this place as Malange. Mahabalipuram is also known by other names such as Mamallapattana and Mamallapuram. The term Mamallapuram means the city of Mamalla, the other name of the famous Pallava Emperor Narasimhavarman I (630-670 CE) who built the famous temples in the city.

Another name by which Mahabalipuram has been known to mariners, at least since Marco Polo's time is "Seven Pagodas" alluding to the Seven Pagodas of Mahabalipuram that stood on the shore, of which one, the Shore Temple, survives. History Neolithic burial urn, cairn circles and jars with burials dating to the 1st century BCE have been discovered near Mahabalipuram.
