The Red Fort was built, in red sandstone, by empror Shah Jahan. The Red Fort, once had the river Yamuna flowing on one side and moats on the other three. Before 1857, the fort was a mini city with palaces, offices, workshops and halls of audience in which about 3,000 people lived. Today, the remains of the palace exists in the form of Mumtaz Mahal, Rang Mahal, Khas Mahal, Diwan-I-Khas, the Hammam, the Lahori Gate and the Shah Burj from where originated the Nahar-e-Bishist (Canal of Paradise) which flowed in a channel through these buildings. The Khas Mahal or the emperor's Palace, also a part of these sections has special rooms for private worship and sleeping. Walking inside, you can find a small bazaar, called the Meena Bazzar, a small part of Chatta Chowk, where all kinds of small items are sold. This was the point where everyone had to dismount from the elephants and walk to the Diwan-I-Am.   The Diwan-I-Khas was the hall of private conversation.

The Hummam (bathing area) has three chambers with a fountain in the middle, even the floor is covered with embroidery in stone. Shah Burj, a place where the emperor held private conclaves and relaxed in privacy pondering over various issues is located in a secluded part of the Qila. It is the rampants of the Lahori Gate where the Prime Ministers of independent India have made their historic speeches.

The Moti Masjid or Pearl Mosque, a white marbled mosque was added by Aurangzeb as his own private masjid. The Fort is enlighted in the evening by the sound & light show, which takes you to the era of the Mughals.
