Picture of the day for November 26, 2016

picture of the day on November 26, 2016: View of a row of corners of the walls of Saksaywaman, a citadel on the northern outskirts of the city of Cusco, historic capital of the Inca Empire, today Peru. The first sections of the citadel were first built by the Killke culture about 1100 and expanded by the Inca from the 13th century. The dry stone walls are composed of huge stones, which boulders are carefully cut by workers to fit them together extremely tightly without mortar. https://commons.wikimedia.org/wiki/File:Sacsayhuam%C3%A1n,_Cusco,_Per%C3%BA,_2015-07-31,_DD_05.JPG
