Which civilization, famous for advanced engineering and extensive road systems, was centered in modern-day Peru?

The Inca civilization, which was centered in modern-day Peru, is renowned for its remarkable achievements in engineering and infrastructure. This civilization developed an extensive network of roads that facilitated communication and transportation across its vast territory, which extended along the western coast of South America. The Incas are particularly known for their sophisticated construction techniques, including the use of stone without mortar and the ability to build structures that have withstood earthquakes.

In addition to their roads, the Incas created impressive architectural feats, such as Machu Picchu, and developed agricultural systems that included terrace farming on steep mountainsides. This combination of engineering prowess and effective resource management allowed the Inca Empire to thrive in a challenging terrain, making them one of the most iconic civilizations in pre-Columbian America. Other civilizations listed, such as the Maya and Aztec, were located in different regions (Mesoamerica) and had distinct characteristics and achievements that do not include the same level of road infrastructure as seen with the Incas.
