Agra- Itimad-ud-Daulah's Tomb

Often described as a "jewel box", sometimes called the "Baby Tāj", the tomb of I'timād-ud-Daulah is often regarded as a draft of the Tāj 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 Tāj Mahal.
