Taj Mahal. An immense mausoleum of white marble, built in Agra between 1631 and 1648 by order of the Mughal emperor Shah Jahan in memory of his favourite wife, the Taj Mahal is the jewel of Muslim art in India and one of the universally admired masterpieces of the world’s heritage. The Taj Mahal is considered the finest example of Mughal architecture, a style that combines elements from Persian, Indian, and Islamic architectural styles. In 1983, the 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. Its refined elegance is a conspicuous contrast both to the Hindu architecture of pre-Islamic India, with its thick walls, corbelled arches and heavy lintels, and to the Indo-Islamic styles, in which Hindu elements are combined with an eclectic assortment of motifs from Persian and Turkish sources.
