Stones of Sacsayhuaman

Click on this shot to get the best perspective in it's large view. The people in this shot give you an idea of the size of these ancient Inca building stones. How they were brought to this high elevation is a question to ponder. Perhaps the most impressive aspect for me is that these stones are joined so tightly that a credit card can not be inserting in any of the joints. This was all done without any mortar or cement. And...word has it that the Inca did not have any Labor Unions!
