WALLS OF RAI PITHORA'S FORT AND JAHANPANAH
AT THE POINT WHERE THEY MEET TOGETHER
Prithviraja III, better known as Prithviraj Chauhan, had extended the Lal Kot by building the 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 ]ahanpanah (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 Pi thora near Hauz Rani village.
