Tomb D is almost identical to Tomb C, situated nearby, but at a larger scale. Tomb D is a mud mortar brick structure. Its square plan measures 30' externally and 27' 6" internally. The tomb has turrets at each of its four corners. The turrets have as many as twelve bands of glazed and unglazed terracotta tiles. Some of these ornamental bands repeat designs from the body of the tombs to create a seamless wrapper effect. The tomb has three arched entrances on the east, south and north side. All the three entrances are faced with identical ornamentation. The mehrab is located on the west wall marked with a double rectangular panel. The interior is faced with bands of alternating glazed tiles, cut bricks, lozenges, chevrons and diaper work. Simple squinches of three-tiered arches in the four corners transform the square lower story (14' high) into an octagon, which becomes the drum or base of the dome. The tomb is in a bad state of decay with most of its dome structure and cupolas of the corner turrets in ruins.
