Built along the mighty Urubamba River, deep in the Andes Mountains, lies one of the most spectacular ruins built by the Inca people. The ruins of Wiñay Wayna, known as "Forever Young" in the Quechua language, were lost to the world until 1940 when they were "rediscovered" by the Wenner Gren Scientific Expedition to Hispanic America. Paul Fejos and his team documented a number of sites on or near the trail that leads to Machu Picchu (known as the Inca Trail).
Sadly, not much is known about what the purpose of the ruins are. However, they are shaped by the typical agricultural terraces seen throughout the Inca territory.
