The Archaeological Survey of India (Delhi Circle) of Ministry of Culture has discovered a hoard of 254 Copper Coins in the premises of Khirki Mosque during the course of conservation of the monument.
This mosque lies on the southern periphery of the village Khirki.
The mosque was built by Khan-i-Jahan Junan Shah, the Prime Minister of Firoz Shah Tughluq (1351-88), and is believed to be one of the seven mosques built by him.
Features of the fort:
Built with rubble stone, and thickly plastered, the Khirki Mosque is double-storeyed. The lower storey consisting only of a series of basement cells.
Battered bastions occupy its four corners, imparting it the look of a fortified building. Gateways project from its three sides, except on the west, each flanked by tapering minarets, the main entrance being from the east.
Corresponding with the openings of cells on the lower storey, the upper storey contains perforated windows (khirkis), which have given it its present name.
This ingenious way of covering the courtyard is repeated only in one other mosque erected by the same builder. These two are the only examples of closed mosques in northern India.
