The Inca Road, also known as the Qhapaq Ñan, is an extensive network of ancient roads built by the Inca Empire in South America. Stretching over 25,000 miles, it connected various regions across present-day Peru, Ecuador, Bolivia, and Chile. The road system facilitated trade, communication, and military movement, playing a crucial role in the empire's administration. Constructed primarily between the 15th and 16th centuries, the Inca Road features impressive engineering, including stone-paved paths, bridges, and tunnels. It traverses diverse terrains, from mountains to deserts, showcasing the Incas' advanced knowledge of agriculture and architecture. Today, parts of the road are recognized as a UNESCO World Heritage Site.
