In 1983, Taj Mahal became a UNESCO World Heritage Site and was cited as "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage."While the white domed marble mausoleum is most familiar, Taj Mahal is an integrated complex of structures and was completed around 1648.
