Which Indian mausoleum made of white marble was built by Shah Jahan?

The Indian white-marble mausoleum built by Shah Jahan is the Taj Mahal.

Shah Jahan commissioned the monument in Agra after the death of his wife, Mumtaz Mahal, in 1631. It was designed as her tomb and later became Shah Jahan’s own burial place. Construction of the mausoleum was largely completed by 1648, while the wider complex was finished around 1653.

The Taj Mahal combines Mughal, Persian, and broader Indo-Islamic design traditions. Its white marble came mainly from Makrana in Rajasthan, and its decoration includes delicate inlay work using semi-precious stones. The complex also contains a mosque, a guesthouse, formal gardens, and a monumental entrance gateway.

A common mix-up is assuming every part of the complex is white marble: the surrounding buildings prominently use red sandstone. Another popular story, that Shah Jahan planned a black-marble twin across the Yamuna River, is generally treated as a legend rather than an established historical plan.
