One of the new Seven Wonders of the World, the spectacular Inca citadel of Machu Picchu is situated at an altitude of 2,380 metres on a saddle between two mountain peaks, and set against a dramatic backdrop of cloud forest covered mountains.

These remarkable ruins became known to the scientific world in 1911, after the American archaeologist Hiram Bingham was led to the site by locals. Perched dramatically 1000 ft above the Urubamba river, Machu Picchu is a UNESCO World Heritage site. It is also the end point of the most popular hike in South America, the Inca Trail.

The story of Machu Picchu is quite a remarkable one; it is still unknown exactly what the site was in terms of its place in Inca life. Current researchers tend to believe that Machu Picchu was a country resort for elite Incas. At any given time, there were no more than 750 people living at Machu Picchu, with far fewer than that during the rainy season. The Incas started building it around AD 1430, but it was abandoned as an official site for the Inca rulers a hundred years later at the time of the Spanish conquest of the Inca Empire.

One thing that is clear is that it was a remarkably well hidden place, and well protected. Located far up in the mountains of Peru, visitors had to travel up long valleys littered with Inca check points and watch towers. Remarkably, the Spanish conquistadors missed the site. However, many people are said to have knowledge of the ancient city as it was referred to in some text found in the 20th century; even so, it was not until Bingham that Machu Picchu was scientifically discovered (he was on a trip sponsored by the Yale University, actually looking for Vilacamba, the last Inca hideout).
