Sadiq Khan was a noble and the son-in-law of Mirza Ghiyath Beg, popularly known as Itmad-ud-Daulah. His tomb is situated on Agra-Delhi road, next to the tomb of his son Salabat Khan, popularly known as Chausath Khambha. Sadiq Khan was an Iranian and served both Jehangir and Shah Jehan. He was appointed Mir-Bakhshi in 1622 and died in 1633. His son Salabat Khan built his tomb between 1633-35. The tomb structure has an octagonal plan and stands on a high square platform. The plan consists of just one big octagonal hall accessible through eight portals, one on each side. However, no cenotaph or real grave has been found in the underground chamber.
This chamber can be seen through a large hole in the centre of the
floor. There is a narrow whispering gallery just above the portals with
three arched and two oblong openings on each side. The total aesthetic
effect of this is marvelous. Brick and masonry are the main construction
materials used while a thick layer of white shell plaster covered the
structure. Exteriors include projecting chhajja supported on brackets
and pinnacles with spiral flutings. The double dome crowns the tomb and
sports an inverted lotus (padmakosha) and a slender Kalash finial on its
