Even just the architecture rises quite literally above all other such structures: viewing it from the outside, one immediately thinks of a wing. The structure seems dynamic, practically weightless—despite weighing far over 1,500 tons. From the inside, the airplanes appear to be sheltered by their own heavenly canopy. The imposing form was achieved via the use of exactly 1,754 pieces of variously sized glass plates, some of them curved, which were joined to form a steel-and-glass construction.
