Exquisite simple proportions of the dome
The outer walls of the Dome form a large octagon. The diameter of the inner rotunda, the height of the drum and the height of the dome are almost the same (19.8 m and 20.1 m). The overall height (54 m) is only slightly more than the overall diameter (52 m) of the building. The ratio of the outer octagon to the height of the dome is 1:3. Suleiman the Magnificent covered the octagon with coloured tiles.The elegant gilded aluminium dome was restored in 1958-64.
