This octagonal tomb with four wide and four narrow sides (Muthamman-i-Baghdadz), stands to the west of Humayun's tomb. It has high recessed arches on all its sides and a high drummed double dome covered with coloured tiles, which has given it its present name, meaning the 'green dome'. Lacking such pre-Mughal features as guldastas, chhajjas and chhatris, architecturally the building is in Central Asian tradition and can be placed in the early Mughal period. With traces of cross walls on whee -shaped
plan and wooden beams preserved in the upper dome, it retains some clues of the method of its construction.
