The Taj Mahal 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 emperor, Shah Jahan, to house the tomb of his favorite wife, Mumtaz Mahal. Ustad Isa and Ustad Ahmad Lahauri are credited to have been the main architects. It is believed that their design embodied much of what the Emperor wanted to express.
