It serves as the symbolic heart of metropolitan Delhi and is known for its bazaars, street food, shopping locations and its Islamic architecture; Jama Masjid being the most notable example, standing tall in the midst of the old city.

The Khooni Darwaza, south of Delhi Gate and just outside the walled city, was originally constructed by Sher Shah Suri.

The main street, now termed Chandni Chowk, runs from the Red Fort to Fatehpuri Masjid.
