Location : 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.
