Mysteries From Ancient Times That Still Defy Explanation

Saksaywaman Fortress Walls

This fortress is so old it predates the Incan empire, although it has not been definitively dated. The stones weigh more than 200 tons and fit together perfectly, as though constructed with modern machinery. The people in the area, which is in Cuzco, Peru, have a legend explaining how the work was done, using a native plant to make the stones lighter and easier to manipulate. The area was probably used as a temple.
