Taken in the Summer of 2010 at Sacsayhuaman, near Cusco
Sacsayhuaman offers some phenomenal examples of Incan masonry, which used no mortar and involved perfect joints that weren’t perfectly on the horizontal or vertical (i.e. the joints had to be matched up on planes of various angles.)
Pisaq (also spelled “Pisac”) is a site of Incan ruins overlooking the Sacred Valley. The Sacred Valley is the river valley of the Urubamba River, which is also called the Willkanuta. This type of terracing is common around Incan sites.
