Agra Fort
Agra Fort is a giant fort made of red stone in Agra, India. Its tall walls go all the way around a city of palaces. Emperors lived there long ago.
Agra Fort is a huge red sandstone fortress beside the Yamuna River in Agra, India. The Mughal emperor Akbar began it in 1565. Its walls, about 2.5 kilometers around, protect palaces, halls and mosques added by later emperors. It was both an army base and a royal home.
Commissioned by Akbar in 1565 on the site of earlier fortifications, Agra Fort is a crescent-shaped red sandstone citadel with 21 m walls and a moat. Shah Jahan and Jahangir added palaces and halls within it, making it, in Britannica's words, a city within a city. It has been a World Heritage Site since 1983.

Discover Agra Fort
Agra Fort is in Agra, a city in India.
It is made of red stone. Its high walls curve around like a giant smile. Inside are palaces, gardens and halls where emperors lived and worked.
Agra Fort stands on the bank of the Yamuna River in the city of Agra, in northern India. It is built of red sandstone and is also known as the Red Fort of Agra. Its walls rise about 21 meters and run about 2.5 kilometers around. A moat surrounds them.
The fort was both an army base and a royal home. When Agra was the capital of the Mughal emperors, the empire was ruled from here. Inside the walls are palaces, audience halls and mosques, so many that it is like a city within a city. The Taj Mahal stands downstream, around a bend in the river.
Britannica describes Agra Fort as a large 16th-century red sandstone fortress on the right bank of the Yamuna, in west-central Uttar Pradesh, which served as military base, royal residence and seat of government while the Mughal capital was at Agra. It is a contemporary of Humayun's Tomb in Delhi, about 200 km to the northwest, and is linked to the Taj Mahal, downstream around a bend of the river, by parkland and gardens.
The walls of the roughly crescent-shaped enclosure run about 2.5 km and rise 21 m (70 ft), surrounded by a moat. UNESCO, which listed the fort in 1983, describes the enclosure as holding the imperial city of the Mughal rulers, with palaces such as the Jahangir Palace and Shah Jahan's Khas Mahal, audience halls such as the Diwan-i-Khas, and two mosques.

A fortress for three emperors
Long ago, an emperor named Akbar built this fort.
His son and his grandson added beautiful palaces inside. One emperor even had to stay inside the fort for the rest of his life.
The Mughal emperor Akbar ordered the fort in 1565, on a spot where older forts had stood. Building reportedly took eight years. Akbar also built a palace inside for his son, Jahangir.
Later emperors kept adding to the fort, especially Jahangir and his son Shah Jahan, who built marble halls and palaces. In 1658 Shah Jahan's own son, Aurangzeb, became emperor and kept his father confined in the fort until Shah Jahan died in 1666.
Britannica records that Akbar commissioned the fort in 1565, on the site of earlier fortifications, and that construction reportedly took eight years. Akbar built Jahangiri Mahal as a private palace for his son Jahangir; many later structures were added by subsequent Mughal emperors, notably Jahangir and Shah Jahan.
The fort also served as a prison: Aurangzeb, Shah Jahan's son and successor as emperor, had him confined there from 1658 until his death in 1666. Aurangzeb also took the Peacock Throne, which had been kept in the fort's Hall of Private Audience, to Delhi, and the Octagonal Tower near that hall had been the residence of Shah Jahan's wife Mumtaz Mahal.
Walls of red sandstone
The builders used red stone for the high walls.
The walls have round towers and a notched top. A deep ditch called a moat runs around the outside.
Akbar's builders made the fort's great walls from red sandstone. The walls curve around in a rough crescent, like a new moon, and are lined with round towers called bastions. Along the top are battlements, a notched edge of stone.
The walls have two gates. The Delhi Gate, facing west, was the original entrance and is decorated with marble inlay. Today visitors come in through the Amar Singh Gate, facing south, the only way in or out. Inside, the buildings recall Persian and Timurid styles, and some later ones are of white marble.
The enclosure walls are of red sandstone, about 2.5 km in circumference and 21 m high, surrounded by a moat, and the plan is roughly crescent-shaped. Britannica notes two access points: the Delhi Gate, facing west, the original entrance, richly decorated with intricate marble inlays; and the Amar Singh Gate, facing south, now the only way in or out of the complex.
Within, Britannica describes buildings reminiscent of Persian- and Timurid-style architecture forming a city within a city. Shah Jahan's Pearl Mosque is made entirely of white marble, and the Khas Mahal's marble walls were once adorned with flowers depicted in precious gems.
Palaces, halls and a palace of mirrors
Inside the fort are palaces and big halls.
One palace has walls covered with thousands of tiny mirrors! In one hall, the emperor listened to people who came to ask for help.
Inside the walls, Jahangir's Palace is the largest home in the fort. In the Hall of Public Audience, the emperor listened to people's requests and met officials. The Hall of Private Audience was for important visitors, and the famous Peacock Throne was once kept there.
Shah Jahan's Pearl Mosque is made entirely of white marble. The Palace of Mirrors has walls and ceilings set with thousands of small mirrors. Near the Hall of Private Audience rises the Octagonal Tower, where Shah Jahan's wife Mumtaz Mahal lived.
Britannica's list of major buildings: Jahangir's Palace (Jahangiri Mahal), the largest residence in the complex; the Pearl Mosque (Moti Masjid) of Shah Jahan, entirely of white marble; the Hall of Private Audience (Diwan-i-Khas), for distinguished visitors, where the Peacock Throne was kept until Aurangzeb took it to Delhi; and the Octagonal Tower (Musamman Burj), residence of Mumtaz Mahal.
In the Hall of Public Audience (Diwan-i-Am) the emperor heard public petitions and met state officials. The Khas Mahal, the emperor's private palace, had marble walls once adorned with flowers in precious gems; to its northeast, the Palace of Mirrors (Sheesh Mahal) has walls and ceilings inlaid with thousands of small mirrors, in two chambers probably used as baths.

The fort was inscribed on the World Heritage List in 1983 under criterion (iii); UNESCO lists the Taj Mahal as a separate site, and describes the fort's 2.5 km enclosure as holding the imperial city of the Mughal rulers, with palaces, audience halls and two mosques. Visitors enter only by the Amar Singh Gate. Among the buildings inside, Britannica highlights Jahangir's Palace, the Pearl Mosque, the halls of public and private audience, the Khas Mahal and the Palace of Mirrors.
The Taj Mahal lies downstream, around a bend of the Yamuna, linked to the fort by parkland and gardens; its own page covers Shah Jahan's tomb for Mumtaz Mahal.
