Taj Mahal stands on the bank of River Yamuna, was built by the fifth Mughal emperor, Shah Jahan in 1631 in memory of his second wife, Mumtaz Mahal, a Muslim Persian princess. She died while accompanying her husband in Burhanpur in a campaign to crush a rebellion after giving birth to their 14th child. The death so crushed the emperor that all his hair and beard were said to have turned snow white in a few months.

When Mumtaz Mahal was still alive, she extracted four promises from the emperor: first, that he build the Taj; second, that he should marry again; third, that he be kind to their children; and fourth, that he visit the tomb on the nniversary of her death. He kept the first and second promises. Construction began in 1631 and was completed in 22 years. Twenty thousand people were deployed to work on it. The material was brought in from all over India and central Asia and it took a fleet of 1000 elephants to transport it to the site.
