Machu Picchu, early morning
Often referred to as "The Lost City of the Incas", Machu Picchu is one of the most familiar symbols of the Inca Empire.
Machu Picchu was declared a UNESCO World Heritage Site in 1983, when it was described as "an absolute masterpiece of architecture and a unique testimony to the Inca civilization". Since it was not plundered by the Spanish when they conquered the Incas, it is especially important as a cultural site and is considered a sacred place. It is also known as one of the "New Seven Wonders of the World".
