The Archaeological significance of the Villupuram District was identified through surface surveys and salvage exploration, which lead researchers to put forward the hypothesis, that Villupuram District would have been the ancient port and anterior to the Indus Civilization. This Archaeological research revealed many Paleolithic and several megalithic sites in the District in order to understand the geological, cultural contexts of the sites and artifacts. The early Tamil epigraphs written in a script on rock were found in Jambai, Edakal, Meltupathi and Alagaramalai. Ancient urns were unearthed from various villages like Thiruvakkarai, Andali, Arumbrampattu etc.
This paper discussed the great phenomenon of present and previous archaeological explorations in Villupuram District. We can understand the antiquity of Tamil Nadu both in time and space and to study the political, social and economic development of the Tamil Nadu during these primarily archaeological and epigraphically sources.
