The Incas built an extensive and sophisticated empire in South America, renowned for its advanced architecture, agricultural terraces, and intricate road systems. Key architectural feats include the citadel of Machu Picchu and the city of Cusco, which served as the empire's capital. They also developed advanced agricultural techniques, such as terracing and irrigation, to maximize crop yields in the challenging Andean terrain. Additionally, the Inca road network, spanning over 25,000 miles, facilitated communication and trade across their vast territory.
