Quila Rai Pithora is known as the first red fort of Delhi. The prince of Sakambhari, Vigraharaja IV captured Delhi from the hands of the Tomar Rajputs in the concluding half of the 12th century. Prithviraj Chauhan, who was the grandson of Vigraharaja IV, built the Qila Rai Pithora, by extending the fortress of Lal Kot, and erecting huge fortifications and moats around it.
Presently, the remains of Qila Rai Pithora have been preserved in a Conservation Park at Mehrauli. This park houses an 18-foot high statue of the great ruler Prithviraj Chauhan and also has a library. The entry to the Quila Lal Pithora is free and open to all. As of now, it is being developed as a tourist place that will have a museum having artifacts belonging to the Mughal era.
