The main square in Cusco:

One theory as to why the Inca built this way is that it protected against earthquakes. Notice that each stone is never a perfect rectangle, at the very least they tend to have a trapezoid shape. This meant that an earthquake would actually shake them together and make the wall stronger. Perhaps why most Inca walls like this are still around today. This twelve angled stone is the keystone in this wall.

After the Inca museum, which was another museum were they don't allow photography, I went for a walk up to Sacsayhuaman, some inca ruins. It is unknown exactly why it was built but there is a theory that it was for their snake god, because it zig zags like a snake. But the stone work is just as incredible as Machu Picchu. A tour guide said that the Spanish believed that the demons helped the Inca build it because they didn't believe that the Inca moved and placed the huge rocks by themselves.
