மலை கொல்லை (குள்ளர் குகை) Dolmens

The Jawadhu Hills, home to the dolmens, have a rich history of human habitation dating back to the Neolithic and Megalithic eras. The 'மலை கொல்லை (குள்ளர் குகை) Dolmens,' also known as 'Kullar Caves' or 'Dwarf Caves,' are ancient megalithic structures believed to be over 4000 years old, originating in the Neolithic Period.

Discovered by the Tamil Nadu State Archaeology Department in 1972, these sites were confirmed as continuous prehistoric settlements by recent excavations in March 2024, which uncovered over 100 megalithic burial sites. Local tribal communities believe dwarfs once inhabited these hills, giving rise to the 'Dwarf Caves' moniker.

Globally, dolmens are prehistoric burial monuments, often communal tombs. The Jawadhu Hills dolmens are unique for their hilltop location, typically found in clusters, constructed from rough-cut stone blocks with capstones. Many are semi-circular with a circular porthole on their eastern side, possibly for prayer offerings.
