Explanation:

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 Mamallapuram. Mamallapuram was one of two major port cities by the 7th century within the Pallawa Kingdom Pallava Kingdom. The town was named after Pallava king Narasimhavarman I, who was also known as Mahamalla. 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, Durga, Vishnu, Krishna and others. The contemporary town plan was established by the British Raj in 1827.
