name the famous monument in delhi made of red sandstone
Red Fort Constructed in 1639 by the fifth Mughal Emperor Shah Jahan as the palace of his fortified capital Shahjahanabad,[3] 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,[citation needed] 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 Fortâ€™s innovative architectural style, including its garden design, influenced later buildings and gardens in Delhi, Rajasthan, Punjab, Kashmir, Braj, Rohilkhand and elsewhere.[2]
History of Delhi The third and greatest Mughal emperor, Akbar, moved the capital to Agra, resulting in a decline in the fortunes of Delhi. In the mid-17th century, the Mughal Emperor Shah Jahan (1628–1658) built the city that sometimes bears his name Shahjahanabad, the seventh city of Delhi that is more commonly known as the old city or old Delhi. This city contains a number of significant architectural features, including the Red Fort (Lal Qila) and the Jama Masjid. The old city served as the capital of the later Mughal Empire from 1638 onwards, when Shah Jahan transferred the capital back from Agra. Aurangzeb (1658–1707) crowned himself as emperor in Delhi in 1658 at the Shalimar garden ('Aizzabad-Bagh) with a second coronation in 1659. After 1680, the Mughal Empire's influence declined rapidly as the Hindu Maratha Empire rose to prominence.[24]
