Biltmore House. -- The Cantilevered Staircase. -- Inspired by the staircase at the Chateau de Blois in the Loire Valley, Biltmore’s grand staircase is a marvel of physics, built using counterbalance. The weight of each of the solid limestone slab steps is offset by the weight of the wall bearing down on it.
