An Archaeological site (C. 400 BC - 1700 AD)
The very old site known as Raja Karna-ka-Qila, is a vast mound about 5-km west-southwest of Thanesar. The mound is about 10 m high from the general ground level. The excavation in the main mound revealed a three-fold series.

Period I: No sherd of the Painted Grey Ware was obtained form the deposits of the period. The earliest occupation in this part of the mound seems to have begun by about the fourth century BC.

Period II: This period was marked by the occurrence of the 'Plain Ware' and 'Red Polished Ware', and may be dated to third century AD. Among the finds, the most notable were three clay sealings, bearing legends in Brahmi script of the early centuries of the Christian era and a few terracotta figurines. Thereafter, the site remained deserted till it was re-occupied in the late medieval times.

Period III: The use of 'lakhauri' bricks and pre-Mughal 'glazed ware' characterized this period. To this period belonged two parallel walls and revetment was of 'lakhauri' bricks. The whole complex seems to have formed part of a late medieval fortification. Another interesting structure of this period was a 'hauz' of 'lakhauri' bricks, plastered with lime.
