DAILY PHOTO: Walls at Sacsayhuaman

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.)
