The Great Pyramid of Meereen is 800 feet tall (243,84 meters),from its huge square base to the lofty apex. A huge bronze harpy once stood at the apex. Like its ancient predecessor, the Pyramid has thirty-three levels, a number which is considered to be sacred to the gods of Ghis. Meereen has a score of lesser pyramids, but none stand even half as tall. The foundations of the pyramid are massive and thick to support the weight of the huge structure overhead. The interior walls are 3 times thicker than the curtain walls of any castle. The outer walls are 30 feet thick (9.14 meters); they muffle the tumult of the streets and keep the heat outside. Consequently, it is cool and dim within. It is always dusk inside the base of the Great Pyramid.
