Lost to the outside world for over 500 years and never found by the Spanish conquistadores, Machu Picchu is the finest example of an Inca citadel anywhere in Peru. Perched on a secluded mountain ridge on the edge of Peru’s Amazon Jungle, its many agricultural terraces and expertly crafted buildings and temples seamlessly merge into the mountainside. A UNESCO World Heritage Site, a New Wonder of the World and simply one of the most beautiful places on the planet, Machu Picchu offers the best insight into a mysterious lost civilization and embodies everything about the mighty Inca Empire.
