On the banks of river Yamuna, rises the crescent-like Agra Fort. Designed and built by Emperor Akbar in 1565 A.D., the fort is surrounded by a 70 foot high wall. It houses the beautiful Pearl Mosque and numerous palaces including the Jahangiri Mahal, Khas Mahal, Diwan-i-Khas, Diwan-i-Am, Machihi Bhawan and Moti Masjid. The fort has four gates and is enclosed by a double battlemented wall of red sand stone.
