The Jama Masjid mosque of Old Delhi is the largest in India, with a courtyard capable of holding 25,000 devotees. It was begun in 1644 and ended up being the final architectural extravagance of Shah Jahan, the Mughal emperor who built the Taj Mahal and the Red Fort.
The highly decorative mosque has three great gates, four towers and two 40 metre high minarets constructed of strips of red sandstone and white marble.
