Shah Jahan sent his architects to derive inspiration from some of the designs of Tomb of Hoshang Shah for the Taj Mahal. The sarcophagus of Hoshang Shah, carved in the form of a casket with receding bands, stands at the centre of a square enclosure surmounted by a large central dome with a small domed turret at each corner. This being the first building of marble in India, Hoshangshah’s Tomb is the most improved example of the Afgani architecture. The chief specialties of the tomb include the extremely balanced structure & proportional tomb, extra ordinary and worth seeing construction of the fine nets of marble; four towers to exhibit the four corners and the umbrella like terrace. That is why, Emperor Shahjahan sent his four famous architects to study and understand the structure of this tomb. One of these architects Ustad Hamid, later on attended the construction of Taj Mahal.
