Khirkee Masjid, Malviya Nagar, South Delhi Khirkee Masjid, built between 1351 and 1358 CE, is located at Khirkee near Malviya Nagar in South Delhi. Built during the reign of Firoz Shah Tughlaq, the mosque is one of the seven mosques commissioned by Khan-i-Jahan Junan Shah, the Prime Minister of Firoz Shah Tughlaq. The mosque is known for its fortress-like appearance, with battered corner bastions, a double-storeyed rubble masonry structure, and perforated stone windows (khirkees) on the upper level, from which it derives its name. Its courtyard is uniquely divided into twenty-five squares, with domed and open sections that provide structural support and natural light, reflecting an innovative design in medieval Delhi architecture. Another hallmark of the Tughlaq architecture ie Multiple domes, is also seen here in the form of nine domes, extant over the northeast corner of the grand mosque.
