The lower view is of the octagonal piazza Chandni Chowk, two thirds of the way along the street that took its name, itself with gateways to the Queen's Gardens (Bagh-i-Begum) to the north and a baths (hamman) to the south. It was the reflection of the moonlight in the central tank that gave the piazza and then the street its name. Watercolor, folio size 25.8 x 19 cm. British Library, London, Add.Or.5475 f.59. In the heart of Old Delhi, Chandni Chowk is a busy shopping area with markets full of spices, dried fruit, silver jewelry and vivid saris, while the narrow side streets are crowded with tiny shops selling essential oils, stationery and traditional Indian sweets. Nearby, the vast Mughal-era Red Fort now houses a museum complex, and the 17th-century Jama Masjid is a huge red-sandstone mosque with towering minarets.
