PIRGHAIB (ON THE RIDGE)-
It was built by Firuz Shah Tughluq and forms part either of his Kushk-i-Shikar (hunting place) or Kushk-i-jahan- Numa (world showing place). The rubble built, double-storeyed structure consists of rooms, chambers, apartments and a hollow masonry cylinder, believed to have been used for
astronomical purposes. A cenotaph lying east to west, in the northern apartment commemorates, according to a tradition, a saint, who used this
room as his chillagah (place of worship), but disappeared at last mysteriously (ghaib).
