Dolmen Circle, located in proximity to Parvatha Vihar and the Pannikadu village, is one of the major attractions of the destination. The hill station of Kodaikanal has marked a place for itself on anthropology map, because of the presence of pre historic remains, which date back to 5,000 BC.
These pre historic remains are the burial and dwelling places of people belonging to the Stone Age and Iron Age, which are known as dolmens and kistavens. The dolmen is made up of two large erect stone slabs, which are topped by larger flat slab. Many dolmens were destroyed, however at present they can be seen intact in two places namely Perumal Peak and Shenbaganur Museum.
