Felix Candela also created a building called The Hills of Cuernavaca. This was built in 1958, and is another perfect example of his hyperbolic paraboloid masterpieces. This building arches high into the sky and taking on a saddle shape, and although it has dramatic curvature it is self-supporting and has visible thinness. Candela was extremely intrigued by geometry as he studied the potential physics of shapes and pushing limits, but still he managed to stretch the imagination. This building rises 70 feet at the taller end, and looks like it is slightly leaning forward and should not be able to balance itself. Finally, the curved edges of the building give it an appearance that looks like an open end of a trumpet, so that the world to see the imagination of Candela.
