Jama Masjid, Delhi

Jama Masjid is the largest mosque in India, constructed between 1644 and 1656 under Emperor Shah Jahan, with a courtyard capable of holding 25,000 worshippers. Its three onion-shaped domes of striped black and white marble and two minarets of red sandstone and marble form the architectural climax of Shah Jahan's Old Delhi. Climbing the southern minaret provides a sweeping view over the density of Old Delhi's rooftops toward the Red Fort to the east.
