The UNESCO World Heritage site is a walled complex, built of large polished stone walls. With Cusco laid out in the shape of a puma, and the hills of Sacsayhuaman symbolizing the head, the zigzagging walls represent the teeth. The three parallel walls are enormous. The component boulders of the walls that protect the ruins within are so tight that even a paper will not slip through.
