Empress Nur Jehan built Itmad-Ud-Daulah's Tomb, sometimes called the Baby Taj, for her father, Ghias-ud-Din Beg, the Chief Minister of Emperor Jahangir. Located on the left bank of the Yamuna river, the mausoleum is set in a large cruciform garden criss-crossed by water courses and walkways. The mausoleum itself is set on a base about 50 meters square and about 1 meter high. The mausoleum is about 23 meters square. On each corner are hexagonal towers, about 13 meters tall. Small in comparison to many other Mughal-era tombs, it is sometimes described as a jewel box. Its garden layout and use of white marble, pietra dura, inlay designs and latticework presage many elements of the Taj Mahal.
The walls are white marble from Rajasthan encrusted with semi-precious stone decorations - cornelian, jasper, lapis lazuli, onyx, and topaz in images of cypress trees and wine bottles, or more elaborate decorations like cut fruit or vases containing bouquets. Light to the interior passes through delicate jali screens of intricately carved white marble.
Many of Nur Jahan's relatives are interred in the mausoleum. The only asymmetrical element of the entire complex is that the cenotaphs of her father and mother have been set side-by-side
