Designed by geometricians, Hagia Sofia’s dome is particularly spectacular. It is supposed to look as if it is being held aloft by a string from the heavens and just lightly resting on the church itself. One of the primary ways this is achieved is that at base of the dome is a series of windows all the way around. Rick Steeves points out that the dome is so tall and wide that Notre Dame in Paris could fit under it and the Statue of Liberty could do jumping jacks there (although not both at the same time).
