It was commissioned in 1632 by the Mughal emperor , Shah Jahan -LRB- reigned 1628 -- 1658 -RRB- , to house the tomb of his favourite wife , Mumtaz Mahal . The tomb is the centrepiece of a 42 acre complex , which includes a mosque and a guest house , and is set in formal gardens bounded on three sides by a crenellated wall .

Described by Nobel laureate Rabindranath Tagore as `` the tear-drop on the cheek of time '' , it is regarded by many as the best example of Mughal architecture and a symbol of India 's rich history . The Taj Mahal attracts 7 -- 8 million visitors a year . In 2007 , it was declared a winner of the New7Wonders of the World -LRB- 2000 -- 2007 -RRB- initiative .
