The Qhapaq Ñan, also known as the Inca Road System, is an extensive network of roads built by the Inca Empire in South America. Stretching over 30,000 kilometers, it connected various regions, facilitating trade, communication, and military movement across the empire, which spanned modern-day countries like Peru, Ecuador, Bolivia, and parts of Chile and Argentina. Designated a UNESCO World Heritage Site in 2014, the Qhapaq Ñan showcases the engineering skills of the Incas, featuring stone-paved paths, bridges, and tunnels. It played a crucial role in the integration of diverse cultures and economies within the empire, reflecting the sophistication of Inca civilization.
