The Taj Mahal (/ˌtɑːdʒ məˈhɑːl/, more often /ˈtɑːʒ/; from Persian and Arabic, "crown of palaces", pronounced [ˈt̪aːdʒ mɛˈɦɛl]) is a white marble mausoleum located on the southern bank of Yamuna River in the Indian city of Agra. It was commissioned in 1632 by the Mughal emperor Shah Jahan (reigned 1628–1658) to house the tomb of his favorite wife of three, Mumtaz Mahal. Construction was completed in 1653 and employed around 20,000 artisans under the guidance of a board of architects led by Ustad Ahmad Lahauri.
