BASTION, WHERE A WALL OF JAHANPANAH MEETS
THE WALL OF RAI PITHORA'S FORT (ADHCHINI) -
Prithviraj III, better known as Prithviraj Chauhan, had extended the Lal Kot by throwing up massive ramparts around it and this enlarged city is
known as Qila Rai Pithora, the First of the so called Seven Cities of Delhi. The ramparts are 5 to 6 m in thickness and their extant height goes as high as 18 m and at places a moat runs on its outer sides. Hauz Rani is one of the three extant gates of Qila Rai Pithora. Muhammad Tughluq after constructing the fort of Adilabad in A.D. 1327 built another fortification, later known as Jahanpanah (Fourth
City of Delhi), which enclosed the suburbs of Delhi lying between Siri and Qila Rai Pithora. It is said that the fortification wall could not be completed but it meets Qila Rai Pithora near Hauz Rani village.
