Agra Fort, the Indian monuments build by red sandstones dominating a bend on the river Yamuna. 2 km from northwest of Taj Mahal was constructed by the Mughals during 1565-1571. The Agra fort was ready by 1571 period of Shahjahan, Akbar's grandson. The Agra fort is crescent shaped, flattened on the east with a long, nearly straight wall facing the river. Fort's colossal double walls rise 69 ft in height and measure 2.5 km in circumference encircled by a moat and contain a maze of buildings that form a small city within a city. The Agra fort contains splendid mosques and palaces in red sandstone and white marble built by two generations of creative builders during the time of Akbar and later Jehangir and Shahjahan.

The wall has 2 gates, the Delhi Gate and the Amar Singh Gate. The original and grandest entrance was through the Delhi Gate, which leads to the inner portal called the Hathi Pol or Elephant Gate.
Now the entrance to the fort is only through the Amar Singh Gate. Public access is limited to the southern part of the fort, which includes nearly all the buildings of tourist interest.
