MAP OF SHAHAJAHANABAD in c.1930 (now Old Delhi)
(From "A Handbook for Travellers in India", 14th ed, John Murray, 1933)

The new city of Delhi, Shahjahanabad, took the shape of a half fan encircled with city walls, putting the fort (Red Fort) on its pivotal point (upper-right in the map). The Jami Masjid (Friday Mosque) was on the lower-left of the fort, connected to the fort through the Delhi Gate. Chandni Chowk Avenue stretched straight to the left (in the direction of Macca) from the Lahore Gate, and still flourishes nowadays as the main shopping street in current Old Delhi.
The reddish part in the map was the urban area for citizens, while the yellowish part was the Cantonment area occupied by the British people before the Independence of India. The overall city formed the usual pattern of a colonial city in that the citadel facing a river was ruled by the suzerainfs army, around which was a eWhite Townf for Europeans and further outside a larger eBlack Townf for the natives.
The British government constructed a railway in parallel with Chandni Chowk Avenue, detaching the northernmost part of the city, and placing Delhi Station in the middle, with the Queen's Garden in front. Subsequently, constructing a further railway for Agra and Bombay on the west of the city wall, it built New Delhi Station between Shahjahanabad and Connaught Place (square). Thus the areas, once full of Charbaghs, were converted into vast railway sites, destroying Shah Jahan's concept for a verdurous city.
