Just an update to this blog I wrote on the Pir Ghaib. Nehru Planetarium has discovered that it may not be a hunting lodge but could have been an observatory. It seems that the Muslim rulers were equally interested in the movement of celestial bodies as their Hindu counterparts. A zenith tube found in the complex could have been used to correct clocks in the 14th century.
Check out this place next Sunday. Instructions to get to the place are here.
