Lal Quila also called the Red Fort is one of the most important monuments of India. It stands on the bank of river Yamuna. The whole structure is made of Red stone. The fort was built by Shahjahan - the Mughal King who also built the famous Taj Mahal - in 1648. Shahjahan called it the Uru-Muhalla. Shahjahan shifted his capital from Agra to Delhi and Red Fort was the new capital. Lal Quila stands at the eastern side of Shahjahanabad and the very name of "Lal Quila" comes from the huge wall that encloses the whole structure. The wall is 2.5 km long and the height varies from 16 meters on the river side to 33 meters towards the city.One of the special attraction of the fort encompasses the whole structure.

The Red Fort was built as the fortified palace of Shahjahanabad, capital of the fifth Mughal Emperor Shah Jahan, in 1648. Named for its massive enclosing walls of red sandstone, it 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.
The Red Fort is considered to represent the zenith of Mughal creativity under Shah Jahan. Although the palace was planned according to Islamic prototypes, each pavilion contains architectural elements typical of Mughal building, reflecting a fusion of Timurid, Persian and Hindu traditions.
