Red Fort
The Red Fort is a huge palace and fort in Delhi, India. Its tall walls are made of red stone. Inside are white marble halls and gardens.
The Red Fort is a palace inside giant red sandstone walls in Delhi, India. The Mughal emperor Shah Jahan had it built between 1639 and 1648 as the heart of his new capital city. Its walls are 23 meters high, and inside are halls of white marble, gardens and a long water channel.
Built from April 1639 to 1648 as the palace fort of Shah Jahan's new capital, Shahjahanabad, the Red Fort takes its name from walls of red sandstone 23 m high enclosing 656 by 328 m. With the older Salimgarh fort it forms a World Heritage Site (2007) that UNESCO sees as the peak of Mughal palace design, later layered with British military buildings.

Discover the Red Fort
The Red Fort is in Delhi, a very big city in India.
Its walls are tall and red. Long ago, an emperor lived inside with his court. Today, visitors walk through its gates and halls.
The Red Fort stands in Delhi, India's capital region. It was built as the palace of Shah Jahan, the fifth Mughal emperor, when he made Delhi his new capital. The first Mughal emperor, Babur, began his reign in 1526.
The fort is named for its massive walls of red sandstone. Inside them were halls where the emperor met his people, private rooms of white marble, gardens and a market. At its height, the emperor's court here housed about 3,000 people. Today it is a World Heritage Site together with an older fort next door, Salimgarh.
The Red Fort was the palace fort of Shahjahanabad, the capital that Shah Jahan, fifth Mughal emperor (reigned 1628–1658), moved from Agra to Delhi. ICOMOS describes it as the focal point of the planned city, at the end of its main axis and beside the Yamuna River, and notes that the court it housed reached some 3,000 people at its height.
UNESCO inscribed the Red Fort Complex in 2007: the Red Fort with the adjoining Salimgarh fort, built by Islam Shah Suri in 1546 on an island in the river and linked by a bridge. It regards the Red Fort as the zenith of Mughal creativity, a fusion of Islamic, Persian, Timurid and Hindu traditions whose planning and gardens influenced later buildings in Rajasthan, Delhi and Agra.

From emperor's palace to independence
An emperor named Shah Jahan built the fort.
It took about nine years. Later, other people used it as an army base. Today, India celebrates its Independence Day here.
Building began in April 1639 and ended in 1648, as part of Shah Jahan's new city. His son, Aurangzeb, added the Moti Masjid, or Pearl Mosque, in 1659–1660, and the last Mughal emperor, Bahadur Shah Zafar, also added to the fort.
After the uprising of 1857, the British took over the fort. They pulled down many of the old buildings and put up army barracks, and turned the Mughal gardens into English-style gardens. When India became independent in 1947, the fort was where independence was first celebrated, and the celebration is still held there today.
Construction began in April 1639 and was completed in 1648 as part of building Shahjahanabad. Aurangzeb added the Moti Masjid in 1659–1660, and Bahadur Shah Zafar, the last Mughal emperor, made further additions. ICOMOS records that the Naubat Khana served as a prison in 1718.
After the events of 1857, Britain captured the fort and made it the headquarters of the British Indian Army. Many major structures were demolished and replaced with colonial military buildings, and the Mughal gardens were redesigned in the English style. UNESCO's criterion (vi) notes that the fort has been a symbol of power since Shah Jahan's reign, witnessed the change to British rule, and was where Indian independence was first celebrated, as it still is. After 1947 the Indian Army controlled the complex; in December 2003 it handed the fort to the Archaeological Survey of India. The Prime Minister addresses the nation from the fort every August 15, Independence Day.
Brick, sandstone and marble
The fort is built of brick.
The bricks are covered with red stone or white marble. Some walls have tiny holes carved in the stone, like lace.
The main building material is brick, covered on the outside with red sandstone or white marble. The fort was laid out on a grid, a pattern of squares, inside an eight-sided shape.
Its builders decorated it with patterns from Persia, Europe and India: shapes made of inlaid colored stones, bright colors and flowing water. Shah Jahan's builders were the first to use tall marble screens called jali, carved with six-sided patterns full of holes, so air and light could pass through.
According to ICOMOS, the Red Fort was the first Mughal palace fort laid out on a geometric grid within an octagon, itself within an octagonal city plan, with pavilions set into the grid. The primary material is brick, clad with sandstone or marble.
Its decoration synthesized Persian, European and Indian motifs into a Shahjahani style of geometric compositions, pietra dura (inlaid semi-precious stone), bright colors and flowing water. Shah Jahan was the first to use tall, complex pierced marble jali partitions based on hexagons. ICOMOS sees all this as the culmination of a Mughal style begun by Babur (1526–1530) and developed by Humayun, who introduced the octagon as a planning form.
Gates, halls and a stream of water
The big gate has two round-sided towers. On top are little white domes.
Inside is a covered market. A stream of water once flowed through the palace rooms.
Visitors and the emperor himself came in through the Lahori Gate, the grand main entrance. It has three stories between two towers, topped by a row of seven arches with small white domes and two slim towers called minarets. Soldiers and workers used the Delhi Gate.
Inside the Lahori Gate is the Chhatta Chowk, a covered market street. Next comes the Drum House, where musicians played to welcome important arrivals, then the Hall of Public Audience, where the emperor sat on a throne under a marble canopy. Beyond it, a row of white marble palace buildings was linked by a water channel that flowed through them all.
ICOMOS describes the walls with bastions topped by domed kiosks and two principal gates: the Lahori Gate, the ceremonial entrance for visitors and the emperor, of three stories between two semi-octagonal towers crowned by a seven-arch arcade with white domes and two minarets; and the Delhi Gate, used mainly by soldiers and staff. The photo shows a gate with these features.
The Lahori Gate opens into Chhatta Chowk, a vaulted arcade once the palace market, leading to the three-story Naubat Khana (Drum House), beyond which only princes could ride. The Diwan-i-Am is an open hall of pillars on a raised plinth, with a nine-arched front; the throne stood under a marble canopy inlaid with semi-precious stones. The white marble pavilions along the river were joined by the Nahr-i-Bihisht water channel, decorated differently in each building.

The Red Fort today
At night, lights make the red walls glow.
People come from all over to visit. Workers take care of the old stones.
Today the Red Fort is looked after by the Archaeological Survey of India, the government group that protects India's important old places. It is a monument of national importance, protected by law.
The fort no longer stands right beside the river. Over time the Yamuna River moved east, and a road now runs where the water once flowed between the Red Fort and Salimgarh. UNESCO says more work is needed to keep the old buildings stable and to make sure the many visitors do not wear them down.
The complex is a monument of national importance under India's ancient monuments law and is managed directly by the Archaeological Survey of India, which took it over from the army in December 2003. ICOMOS reported in 2007 that it drew several million visitors a year. UNESCO notes that conservation has improved but that much more work is needed to stabilize the property and keep visitors from contributing to its decay.
The largest changes to its setting came when the Yamuna shifted east (its old line between the two forts is now the Inner Delhi Ring Road) and when a railway divided Salimgarh. The photo shows a main gate lit at dusk, its two towers and domed kiosks glowing against the evening sky.

Next door is an even older fort, built on an island.
Salimgarh, the fort next door, was built in the 1540s on an island in the river, and a bridge links it to the Red Fort.
Salimgarh, which UNESCO dates to 1546 under Islam Shah Suri (ICOMOS says construction began in 1544), stood on a river island; during British rule its old bridge was replaced by another in a different place, and a railway now runs through it.
