Red Fort Complex, Delhi

In 1638 Shahjahan transferred his capital from Agra to Delhi and laid the foundations of Shahjahanabad, the seventh city of Delhi. It is enclosed by a rubble stone wall, with bastions, gates and wickets at intervals. Of its fourteen gates, the important ones are the Mori, Lahori, Ajmeri, Turkman, Kashmiri and Delhi gates, some of which have already been demolished. His famous citadel, the Lal-Qila, or the Red Fort, lying at the town's northern end on the right bank or the Yamuna and south of Salimgarh, was begun in 1639 and completed after nine years.

The Red Fort is different from the Agra fort and is better planned, because at its back lies the experience gained by Shahjahan at Agra, and because it was the work of one hand. It is an irregular octagon, with two long sides on the east and west, and with two main gates, one on the west and the other on the south, called Lahori and Delhi gates respectively. While the walls, gates and a few other structures in the fort are constructed of red sandstone, marble has been largely used in the palaces.
