Incan road system
The Incan road system, known as the Qhapaq Ñan, was an extensive network of roads covering over 25,000 miles across the Andes mountains in South America. Built around the 15th century, it connected the vast Inca Empire, facilitating communication, trade, and military movement. The roads varied from well-paved paths to rugged trails, featuring impressive stone bridges and staircases. This infrastructure enabled the Incas to efficiently manage their territory and integrate diverse cultures, making it one of the most remarkable achievements of pre-Columbian society. The Qhapaq Ñan is now recognized as a UNESCO World Heritage site.
