The crowning jewel of Indo-Islamic architecture, the Taj Mahal is one of the world’s most beautiful and beloved structures. The monument was built in Agra, India, for Mumtaz Mahal, the favorite wife of Mughal emperor Shah Jahan. Construction of the tomb began in 1632 and employed more than 20,000 laborers for 20 years. During the reign of Shah Jahan, the structure was known simply as the rauza, the tomb. Later, the mausoleum would be called the Taj Mahal, a derivative of the name Mumtaz Mahal
