Kalu Saraj Masjid is one of the seven mosques built By Khan-I-Jahan, the Prime Minister of Feroze Shah Tughluq. It is situated in Kalu-Sarai, a small village about 500m northwest of Bijai-Mandal.
This rubber-built, but plastered mosque has seven arched openings in the facade of its prayer hall. Some of them have now collapsed. The prayer hall is surmounted by a series of domes in the Tughluq style.
Indira Gandhi International Airport and New Delhi Railway Station are the nearest airport and railway station.
