Attirampakkam or Athirampakkam village is located 60 kilometers away from Chennai, Tamil Nadu, India. This site is oldest prehistoric stone tool culture site in India.
Attirampakkam forms one of the classic sites in the history of Indian Paleolithic archaeology. Discovered by the British geologist Robert Bruce Foote in 1863 (Foote 1866), it was sporadically investigated for over a century (Krishnaswami 1938; I.A.R 1965-67). Significant conceptual developments in Indian prehistory and Quaternary studies had their origin in research at this site, which was also characterized as a type-site of the Acheulean handaxe-based 'Madras Industries'. Situated in the Kortallayar river basin, Tamil Nadu, Attirampakkam is one of numerous Lower and Middle Paleolithic sites in the region (Pappu 2002). At present, gullies and rain rills erode tools over an area of around 50,000m².
