The ancient Inca empire was extended along a huge band of territory west of South America that the current southern Colombia reaches a height of Santiago de Chile. This territory in which they lived many different peoples was well managed by the capital Cusco thanks to a highly branched system of roads: the "suyos" so they were called the four main arterial roads of the Empire, set off from the main square of Cusco to reach the furthest reaches , other roads were built across to connect to each other and then to the coast, mountains , mountains the forest.
After five centuries, many of these roads still exist, if some parts are missing, in fact, some are still used by the people of the mountains, others are modeled on the path of the existing roads. For several years in Peru, by the Ministry of Culture is an ongoing study to identify and exploit paths, eight of which were made official in the application to Unesco Heritage.
Along the suyos there are still many archaeological and above all there is an Andean world alive and well, a great people from a strong cultural identity, deeply rooted in the ancient past, but with all the contradictions of nowadays, looking to the future.
