It is believed to be the tomb of an emperor's of daughter whose name is not known. It is a square building built entirely of grey coloured sandstone. It must have originally been a tiny and beautiful structure as glaned now partly by its wavy brackets supporting the eaves and by the bands of the geometrical designs inlaid with blue enamels. From extant remains, it appears that it was covered by a single dome, each side of which has series of five closed ogee arches resting on 20 pillars it is dated A.D. 1420-35.
