Constructed in 1639 by the fifth Mughal Emperor Shah Jahan as the palace of his fortified capital Shahjahanabad, (2) the Red Fort is named for its massive enclosing walls of red sandstone and is adjacent to the older Salimgarh Fort, built by Islam Shah Suri in 1546. The imperial apartments consist of a row of pavilions, connected by a water channel known as the Stream of Paradise (Nahr - i - Bihisht). The fort complex is considered to represent the zenith of Mughal creativity under Shah Jahan, and although the palace was planned according to Islamic prototypes, each pavilion contains architectural elements typical of Mughal buildings that reflect a fusion of Timurid and Persian traditions. The Red Fort 's innovative architectural style, including its garden design, influenced later buildings and gardens in Delhi, Rajasthan, Punjab, Kashmir, Braj, Rohilkhand and elsewhere.
