Lying
about 800m east of the Khirki-Masjid
and forming part of the enclosure-wall of Jahanpanah,
Satpula is a weir, built by Muhammad Shah Tughluq, to regulate the
impounded waters for purposes of irrigation .
It is a unique structure, with eleven openings, two at each end being of
a subsidiary nature, and the remaining ones giving it its present name,
which means 'seven bridges, or 'bridge with seven openings'. The sides of
the openings are provided with grooves for sliding the shutters.
At each end is a tower, with an octagonal chamber within, once utilized
for a school, from which the monument derives
its alternate name of 'madrasa'.
