The Red Fort Complex was built in 17th century as the palace fort of Shahjahanabad, the new capital of the fifth Mughal Emperor of India. Named for its massive enclosing walls of red sandstone, it is adjacent to an older fort, the Salimgarh with which it forms the Red Fort Complex. The private apartments consist of a row of pavilions connected by a continuous water channel, known as the Stream of Paradise. The Red Fort is located on the western bank of Yamuna. It is surrounded by a wall of around 2,4 kilometers in circumference. The elevation of the wall varies from 18 to 33 meters. The Red Fort exhibits the outstanding architectural brilliance of the Mughal Era. This fascinating monument boasts imposing audience halls, a bazaar where the royal family used to shop, marble fortresses, baths, plazas, and a mosque.
