Tomb of Itimad-ud-Daulah (Baby Taj)

In the shadow of its great neighbor, the Taj Mahal, stands a building that architectural historians call "the key to all Mughal aesthetics of the 17th century." The Tomb of I`timad-ud-Daulah, built between 1622 and 1628, was an architectural breakthrough: for the first time in India, white marble completely replaced red sandstone, and the technique of inlay work with semi-precious stones reached an unprecedented level.
