Qila Rai Pithora (1160-1192)

The Chauhan prince of Sakambhari, Vigraharaja IV captured Delhi from the Tomar Rajputs in the latter half of the 12th century. The grandson of Vigraharaja IV, Prithviraja Chauhan III, built Qila Rai Pithora, the first city of Delhi, by extending the citadel of Lal Kot, and constructing huge ramparts and moats around it. The city derived its name from the title of Prithviraja Chauhan and thus came to be known as Qila Rai Pithora,The ruins of Qila Rai Pithora can be seen as you take left turn from Aurobindo Marg towards Saket Some remains have been conserved in a Conservation Park developed by Tourism Ministry. The park has an 18-foot high statue of Prithviraj Chauhan. The ruins of the ramparts of the extended city are rubble-built and are 5 to 6 meters in thickness, with a height of 18 meters on some sides and are surrounded by a wide moat from the outside. The city had a number of imposing gateways and bastions. According to Timur, Qila Rai Pithora had 13 gates.
