Taj Mahal is regarded as one of the seven wonders of the world.
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 at Agra, India. 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.
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.
