Sacsayhuaman

The huge Inca walls at Sacsayhuaman overlook Cusco, a testament to the architectural ingenuity of the Incas.

Today visitors can appreciate the ingenuity of the design, thanks to the imposing zig-zagging walls which remain intact. Put together like a puzzle, the stones of all shapes and sizes form structures so perfect in their design that is mind-boggling to contemplate anyone being capable of such a feat of engineering, especially without the tools and equipment on hand today (its baffling even how some of the stones got there).
