English: This photograph shows Chandni Chowk, the principal street of Shahjahanabad, the seventh city of the seven historical cities of Delhi. The sides of the road are lined with shops and artisans selling their wares. The road was built in 1650 by Jahanara Begum, the daughter of the emperor Shah Jahan. It led from the the Red Fort, Shah Jahan’s fortified palace, and was 40 yards wide and 1,520 yards long. Originally, a canal ran the entire length of the road and into the Fort, providing water for drinking and irrigation. The canal fell into disuse and was covered over by the British between 1840 and the 1860s. This photograph shows the raised cement bed that runs through the centre of the road where the canal used to be.
