All over Hyderabad and surounding areas there are prehistoric monuments ascribed to the megalithic peoples. They were skilled in handling large granite slabs mainly found in their tombs. The stone tombs are usually 3 metres underground and are marked on the surface by a circle of large rounded boulders. In Hyderabad area they are dated variously from 300 BC to 400 AD by archeologists, who say similar constructions in the sandstone area to the south date from 1300 BC.
