Red fort also known as Lal Quila is one of examples of superior architecture that was mastered by the builders of Mughal period. The Red fort of Delhi stands distinctively because of its exclusive construction. The fort covers a huge area with its long stretched red sandstone boundary walls which is nearly 1.5 miles long 60 ft high. Within its compound it includes a series of palaces which are known as Diwan-e-khaas, Diwan-e-aam, Nazr-e-Behist, Zenana., Moti Masjid, Hayat Bakhsh Bagh. With these prominent buildings the compound of red fort is further decorated with high quality Mughal gardens, and a number of fountains that used to serve the purpose of providing water to the palace which was not only used for drinking purpose but also for cooling the place during the summer season.

Red Fort is one of the rare palaces of Mughal dynasty which was built of red tiled sandstone bricks that form the boundaries of the fort stretching it throughout the bank of Yamuna Rivar. The fort receives its name from the huge red stone wall that covers the corners of the palace. The wall is 1.5miles long, and varies in height from 60 feet on the riverside to 110 feet towards the city. Measurements have shown that the plan was generated using a square grid of 82m. The fort lies along with original course of Yamuna River that used to supplies the moats. The wall at its north-eastern corner is adjoining to an older fort, the Salimgarh, a defense built by Islam Shah Sur in 1546. The ramparts were formidable, eight meters high and six kilometres long, a veritable city overlooking another city, Delhi. There were seven gates opening onto the main highways of the Empire- the Kashmiri, Lahori, Noori, Kabuli, Turkmeni, Ajmeri, and Akbarabadi (Agra) gates. Three of them led via circular stairways to the banks of the Yamuna.

Red fort is further protected by a belt of flat sandstone, so that any assailants would first have to scale the outer ramparts and then cross this plain, where they would be easy targets, before reaching the actual palisade. The design of the inner fort was sober, being a rectangle cut in four sections, corresponding to the four points of the compass. The private apartments for the male members of the royal family were located on the north side and overlooked the banks of Yamuna to receive maximum cooling. Their facade skirted the Hayat Bagh and the Mahtab Bagh. In the opposite section was the Zenana, an intricate arrangement of baths, gardens, courtyards, and pools. The magnificent halls of audience were located in the heart of the fortress, the main section stretching from the Yamuna courtyards to the Western Gate and the Delhi Gate. To give primary access to visitors, the main bazaar was located outside.

Red fort along with these include Diwan-i-Khas was a magnificent structure with huge vault-like roof from where golden chains were suspended to decorate the fort at night On the walls there were embroidered velvet drapes and tapestries, and decorative swords, shields, and lances adorned the upper portions. Along with this there is Diwan-i-Am for the common people who were restricted to enter Diwan -e- Khaas. There was a huge awning, embroidered with gold, to protect the visitors from the sun. Above the throne there was a gigantic canopy, woven in the imperial workshop of Ahmednagar to the personal instructions of the Emperor himself, which rested on four silver masts, 20 meters high.

Red fort also includes wide network of canals, called the Nahar-i-Bahisht, running through it, which cooled the place in summer. This canal had been dug in Akbar`s time and was fed by the Yamuna. It irrigated the whole palace, running through many channels to feed fountains falling in cascades in the gardens, filling pools covered with water lilies, and baths. The water reflected in the myriad spangles of the Shish Mahal and in the large mirrors of the sensual bedroom of Shah Jahan. Out in the middle of the Yamuna River, on a small sandbar, was a somewhat ungainly and desolate structure. Built in the time of Akbar, it had bare, steep walls, and the water lapped around the blackened and moss-grown lower portion of its bulwarks. Besides these, the Red Fort also houses the Moti Masjid, Hammam, Tasbih Khana and Mumtaz Mahal among others.

Thus as one of the superior architecture this palace has been one of most attractive monument of the time.
