The Tajo Mahal ( Crown of Palaces ) is an ivory-white marble
mausoleum on the south bank of the Yamuna river in the
Indian city of Agra. It was commissioned in 1632 by the Mughal emporer,
Shah Jahan to house the tomb of his favorite wife, Mumtaz Mahal.
The tomb is the centrepiece of a 42-acre complex, which includes
a mosque and a guest house, and is set in formal gardens 
bounded on three sides by a crenellated wall.
