Not
far from the Begampuri-Masjid
to its north lies Bijai-Mandal, an unusual rubble-built massive octagonal
structure on a high platform, with sloping sides in the Tughluq fashion
and a doorway at each cardinal point.
A temporary cover could be fitted on poles at the southwestern corner of
its roof, while there also existed perhaps an open pavilion. Immediately
to its east lie the remains of an arcaded residential building, which
apparently formed part of a mansion.
The purpose of the building, is however not clear. It is regarded as a
bastion of Jahanpanah by some, while it is believed to have been used
later as his residence by Shaikh Hasan Tahir, a saint of Sikandar Lodi's
reign (1489-1517). Muhammad Shah Tughluq (1325-51) is said to have used it
as a tower for reviewing his troops.
