Red Fort is also known as Delhi Fort, Lal Qil'ah or Lal Qila. Lal means Red and Qila means Fort that's why it is called as Red Fort. Red Fort is another most spectacular pieces of Mughal Architecture. Red Fort was built by the Shah Jahan, a Mughal Emperor between 1638 and 1648, the Red Fort has walls extending up to 2 kms. in length with the height varying from 18 mts. on the river side to 33 mts. on the city side.

The Red Fort stands at the eastern edge of Shahjahanabad, and Red Fort also gets its name from the massive wall of red sandstone which defines its eight sides. There are two halls in the Fort named Diwan-i-Aam and Diwan-i-Khas.

Diwan-i-Aam is the hall of public audience where Mughal Emperor would sit on a marbled paneled alcove, studded with gems, and hear complaints of the common people. Diwan-i-Khas is the Hall of Private Audience, where private audiences were granted.

In Red Fort, there is also a Rang Mahal which is also known as the 'Palace of Colors'. Rang Mahal holds a spectacular Lotus shaped fountain, made out of a single piece of marble, and housed the Emperor's wives and mistresses. The other attractions enclosed within this monument are the hammams or the Royal Baths, the Shahi Burj, which used to be Shahjahan's private working area, and the Moti Masjid or the Pearl Mosque.

There are two main entrances of the Red fort; the Delhi Gate and the Lahori Gate. Lahori Gate takes its name from the fact that it faces to Lahore, which is now in Pakistan. The main entrance opens on to the Chatta Chowk, a covered street flanked with arched cells that used to house Delhi's most talented jewellers, carpet makers, weavers and goldsmiths.

This arcade was also known as the Meena Bazaar. This bazaar has an excellent collection of antiques, miniature paintings and skillfully crafted fake ivory jewellery. The bazaar also sells some fabulous carpets beautifully woven. Just beyond the Chhata Chowk, is the heart of the fort called Naubat Khana, or the Drum House. Musicians used to play for the emperor from the Naubat Khana, and the arrival of princes and royalty was heralded from here.

The fort is octagonal in shape, like most Islamic buildings in India. The north of the fort is connected to the smaller Salimgarh fort. The Red Fort is an intimidating structure.

To its north lies a large formal garden, the Hayat Bakhsh Bagh, or 'Life-Bestowing Garden', which is cut through by two bisecting channels of water. A pavilion stands at either end of the north-south channel, and a third, built in 1842 by the last emperor, Bahadur Shah Zafar, stands at the center of the pool where the two channels meet.

There is also a Swatantra Sangrahalaya. It is a museum which presents the brief history on Indian Independence and also highlights the main incidents of contributions of prominent leaders of the country. It houses the idols of the leaders, chronological pictorial representation of the struggle and maps of India in different centuries. The museum also contains souvenirs, tokens and relics of historical importance.

Red Fort is located on Netaji Subhash Marg, near Chandni Chowk in Old Delhi. Red Fort is open on all days except Monday from 10am to 4pm.
