Commissioned in 1632 by the Mughal emperor Shah Jahan to house the remains of his cherished wife, the Taj Mahal stands on the southern bank of the Yamuna River in Agra, India. The famed mausoleum complex, built over more than 20 years, is one of the most outstanding examples of Mughal architecture, which combined Indian, Persian and Islamic influences. At its center is the Taj Mahal itself, built of shimmering white marble that seems to change color depending on the sunlight or moonlight hitting its surface.
