Excavations have opened up rich hidden stores of
information on ancient cultural practices, values, rituals and beliefs. The Indus valley
civilization is identified with the Tamil civilization on the basis of the architectural
remains, utensils, coins, etc excavated from the Mohanjedaro and Harappa region. The
excavations at Arikkamedu (அரிக்கமேடு) near Pondicherry and ஆதிச்சநல்லூர் near
திருநெல்வேலி have also given lots of clues to
the ancient Tamil Culture.
