Raja Karna-ka-Kila is an ancient site, located about 5 km south-west of
Thanesar, in
Haryana. It is about 10 meters high. Excavations in this mound unveiled a three fold sequence. This mound is believed to have occupied by about the 4th century BC.
Period II dates back to 3rd century BC. Noteworthy of the antiquities of this period are red polished ware, clay sealings, Brahmi script and terracotta figurines.
Period III is characterized by the remains of 'lakhauri' bricks and pre-Mughal 'glazed ware'. Two parallel walls and revetment made of lakhauri bricks are believed to be the ruins of late medieval fortification. Another interesting structure of this period is a 'hauz' of lakhauri bricks, plastered with lime.
The excavations of the nearby mound, located 200 m east of the main mound, revealed the existence of protohistoric habitation. A twin roomed structure made of mud brick walls was identified. The bigger room consists of a fireplace, refuge pit, oven and corn bin. Smaller room is a square structure and has an entrance. Some of the unique findings from here are crystal, jasper and a figurine of stag.
