Chandni Chowk originally meaning moonlit square or market, is one of the oldest and busiest markets in Old Delhi, now in central north Delhi, India. Built in 17th century by the great Mughal emperor of India Shah Jahan and designed by his daughter Jahan Ara, the market was once divided by canals (now closed) to reflect moonlight, and it remains one of India's largest wholesale markets.
It is a famous market known all over India. Google India helps Delhi's iconic Chandni Chowk market go online. They approached each of 2500 stores and even have opened common website for all the shops.
