The Incas built a notable civilization in western South America in the fifteenth and sixteenth centuries. The center of their empire was in present-day Cuzco, Peru. Machu Picchu is an ancient fortress city of the Incas in the Andes Mountains near Cuzco. Built on the steep slopes at the crest of the Andes Mountains, with terraced scientific and agricultural areas, Machu Picchu features wonderful, almost jointless stonework. The Incas were superb craftsmen and thoughtful architect-engineers.

On July 7th, 2007, Machu Picchu was voted as one of New Open World Corporation's New Seven Wonders of the World.
