The discovery of Mach Picchu celebrated its 100 year anniversary with a gorgeous show of dance , lights, fireworks, and music.  Peru president Alan Garcia was among 200 guests to attend the event.  The 'lost city' was found on July 25, 1911 and was voted as one of the New Seven Wonders of the world four years ago. 

The event was limited to 700 guests due to concerns regarding risk of damaging   the ancient citadel and farmlands.  The Urubamba valley hosts 250,000 visitors a year at its southern Lima location. 

Peru's Machu Picchu was discovered by American explorer Hiram Bingham in 1911.  It was then that Bingham made a second visit and began to collect artifacts for the Yale Peabody Museum.  Over 45,000 objects were collected.  Legal battles between Peru and Yale began in 2008 in fighting for custody of the presumably looted objects Bingham obtained.  Yale agreed to return the objects to Peru where the objects will be stored at the Casa Concha of the Universidad Nacional San Antonia Abad, Cusco.
