Amar Singh Gate, one of two entrances into Agra's Red Fort
Agra Fort (sometimes called the Red Fort), was commissioned by the great Mughal Emperor Akbar in 1565, and is another of Agra's World Heritage Sites. A stone tablet at the gate of the Fort states that it had been built before 1000 but was later renovated by Akbar. The red sandstone fort was converted into a palace during Shāh Jahān's time, and reworked extensively with marble and pietra dura inlay. Notable buildings in the fort include the Pearl Mosque or Motī Masjid, the Dīwān-e-'Ām and Dīwān-e-Khās (halls of public and private audience), Jahāngīr's Palace, Khās Mahal, Shīsh Mahal (mirrored palace), and the Musamman Burj.[citation needed]
The forbidding exteriors of this fort conceal an inner paradise. The fort is crescent shaped, flattened on the east with a long, nearly straight wall facing the river. It has a total perimeter of 2.4 kilometres (1.5 mi), and is ringed by double castellated ramparts of red sandstone punctuated at regular intervals by bastions. A moat 9 metres (30 ft) wide and 10 metres (33 ft) deep surrounds the outer wall.
Chhatrapati Shīvajī visited the Agra Fort, as a result of the conditions of the Treaty of Purandar entered into with Mirzā Rājā Jaisingh to meet Aurangzeb in the Dīwān-i-Khās (Special Audience Chamber). In the audience he was deliberately placed behind men of lower rank. An insulted Shīvajī stormed out of the imperial audience and was confined to Jai Sing's quarters on 12 May 1666. Fearing the dungeons and execution he escaped on 17 August 1666. A heroic equestrian statue of Shīvajī has been erected outside the fort.
The fort is a typical example of Mughal architecture, effectively showing how the North Indian style of fort construction differed from that of the South. In the South, the majority of forts were built on the seabed like the one at Bekal in Kerala.[1 Hawa Mahal | Hawa Mahal or "Palace of the Winds", Jaipur, 16 December 2008 | | |
