In the beautiful old city of Cusco, Peru, an immense fortress was built by huge stone blocks weighing upto 300 tons. There isn’t any such record on how these stones were actually cut and moved to put into that place. These stones are so well placed that some of them won’t even let a single piece of paper come between them.
Saksaq Waman is an ancient Inca ruin at an altitude of 3,701 meters and it is walled with mystery near Cusco. “A good example of Inca stonework at Sacsayhuamán, Peru. They cut and hauled huge stones to make walls like this, and fit them together — without mortar! — so tightly that you coudn’t get a knife-tip or a piece of paper between them. Solid enough to have survived tremendous earthquakes.”
