India, Uttar Pradesh, Agra. Visitors at the Taj Mahal. The Taj Mahal was built by a Muslim, Emperor Shah Jahan (died 1666 C.E.) in the memory of his dear wife and queen Mumtaz Mahal. It is an 'elegy in marble' or some say an expression of a 'dream.' Taj Mahal (meaning Crown Palace) is a Mausoleum that houses the grave of queen Mumtaz Mahal at the lower chamber. The grave of Shah Jahan was added to it later. Taj Mahal was constructed over a period of twenty-two years, employing twenty thousand workers. It was completed in 1648 C.E. at a cost of 32 Million Rupees. The construction documents show that its master architect was Ustad 'Isa, the renowned Islamic architect of his time. The documents contain names of those employed and the inventory of construction materials and their origin. Expert craftsmen from Delhi, Qannauj, Lahore, and Multan were employed. In addition, many renowned Muslim craftsmen from Baghdad, Shiraz and Bukhara worked on many specialized tasks.
