Qhapaq Nan, known as the Great Inca Road, is an ancient network of roads spanning more than 8,000 miles, running through the heart of the Andes, from the ocean and deserts all the way to Machu Picchu. Constructed hundreds of years ago during the Inca Empire, this vast transportation network still weaves its way through modern-day Peru and Ecuador. An astonishing feat of engineering, it connected Inca cities, administrative centers, agricultural and mining areas as well as ceremonial centers and sacred spaces.
