CHANDNI CHOWK :- One of the main market of Delhi is located opposite the Red Fort. But today the place is very crowded and congested. On one end of Chandni Chowk is the Fatehpuri Mosque which was erected by the wives of Shah Jahan. Opposite the old police station or the Kotwali is the Sunheri Masjid from where Nadir Shah ordered his troops to plunder and massacre Delhi.
