Photograph from an album of 80 albumen prints taken by Eugene Clutterbuck Impey. This view looks south along the river Yamuna towards the Red Fort in Delhi, with the walls of Salimgarh on the left, connected by a bridge. The Mughal Emperor Shah Jahan (reigned 1628-58) moved his capital from Agra to Delhi in 1638. He then set about building a new city as his seat, embellished with suitably magnificent buildings. The city, called Shahjahanabad, came up in 10 years and was protected by walls pierced by fourteen gates. Between the city and the river Yamuna, Shah Jahan built his residence, the fortified palace of red sandstone called the Lal Qila or Red Fort. It was modelled on the fort at Agra and begun in 1639 and completed in 1648, within its walls were exquisite marble buildings and gardens. The walls of the fort tower over the flat banks of the Yamuna and it still dominates the area (now known as Old Delhi). The edifice still holds symbolism in the imagination of the people as the seat of the ruler, and it is from here that the Prime Minister of India addresses the nation on 15th August, Independence Day.
