Jama Masjid Delhi is the country's largest and perhaps its most magnificent mosque. The mosque is the final architectural extravagance of the Mughal Emperor Shah Jahan with a courtyard capable of holding 25,000 devotees. The mosque measures 65m by 35m, and its court forms a square of 100m. Built in 1656. Its spacious courtyard holds thousands of the faithful who offer their prayers here. It is said that Emperor Shahjahan built Jama Masjid at the cost of Rs 10 crore and it can be called as the replica of Moti Masjid in Agra
On the east, this monument faces the Red Fort and has three gateways, four towers and two minarets. It is constructed of alternating vertical strips of red sandstone and white marble. In the three domes white marble has been used extensively and they have been inlaid with stripes of black.
The structure was placed on a high platform so that its magnificent facade would be visible from all the adjoining areas. Broad flights of steps lead up to the imposing gateways in the north and the south. Wide staircases and arched gateways are the hallmark of this popular mosque. The main prayer hall on the west side is adorned by a series of high cusped arches, standing on 260 pillars which support about 15 marble domes at various elevations. It is said that Emperor Shahjahan built Jama Masjid at the cost of Rs 10 crore and it can be called as the replica of Moti Masjid in Agra
