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.
