The Chandni Chowk, also known as Moonlight Square is one of the oldest and busiest markets in Old Delhi, India. It is located close to the Old Delhi Railway Station. The Red Fort monument is located at the eastern end of Chandni Chowk. It was built in the 17th century by Mughal Emperor of India Shah Jahan and designed by his daughter Jahanara. The market was once divided by canals (now closed) to reflect moonlight and remains one of India's largest wholesale markets.
