Tomb of I'timād-ud-Daulah is a Mughal mausoleum in the city of Agra in the Indian state of Uttar Pradesh. Often described as a "jewel box", sometimes called the "Bachcha Taj" or the "Baby Taj", the tomb of I'timād-ud-Daulah is often regarded as a draft of the Taj Mahal.
Along with the main building, the structure consists of numerous outbuildings and gardens. The tomb, built between 1622 and 1628, represents a transition between the first phase of monumental Mughal architecture – primarily built from red sandstone with marble decorations, as in Humayun's Tomb in Delhi and Akbar's tomb in Sikandra – to its second phase, based on white marble and pietra dura inlay, most elegantly realized in the Taj Mahal.
The mausoleum was commissioned by Nur Jahan, the wife of Jahangir, for her father Mirzā Ghiyās Beg, originally a Persian Amir in exile, who had been given the title of I'timād-ud-Daulah. Mirzā Ghiyās Beg was also the grandfather of Mumtāz Mahāl, the wife of the emperor Shah Jahan, responsible for the construction of the Taj Mahal. Nur Jahan was also responsible for the construction of the Tomb of Jahangir in Lahore.
It is noticeable for the first use of pietra dura technique.
