A Famous place in Peru, South America for ancient retreat city up to the Andes Mountain. The remnant of the sun city on difficult path now accessible by winding road from Agua Caliente. A small city reach by Peru Rail from Cusco. A full day journey from Cusco by Train then bus was breathtaking journey on changing elevation in narrow passage. There must a very good reason to build such city hundreds years ago in this remote mountain. Even with my current standard, would say unthinkable. That's why so attractive and appealing to visit and to know in person far from my place in middle-east desert.
