Story goes that the emperor was grief stricken when he lost his beloved third wife, Mumtaz Mahal. It took several thousands of craftsmen, artisans and about twenty years to construct it. The masons, stonecutters, carvers, inlayers, calligraphers, painters and others were brought from the entire empire as well as from Iran and Central Asia. Semi-precious stones were used for inlay ornamentation. It later became the mausoleum of Shah Jahan too. This is a huge tourist attraction with one to two million tourists visiting it every year.
