The “Valle Sagrado de los Incas” is a fertile valley close to Cusco, which was the center of the Inca empire. It was the Incas heartland, their “sacred valley” which belonged directly to the emperor, and they built many important monuments and cities there, Machu Picchu being the most remote of it.
One very special place is Moray, where they used natural depressions in the land to build circular shaped terraces at different levels, which thru the interplay of sun, shade and wind created many different climate zones in one place. It was the agricultural laboratory of the Incas and they used it to breed and grow crops for many of the different climatic areas in their vast empire. I liked it a lot to take pictures as you can see.
