Spanish conquistadors couldn’t believe their eyes while exploring the rugged terrain of the Andes during their invasion of Peru. On entering Inca territory in the 16th century, they were bowled over by the advanced road system known as the Qhapaq Ñan . However, the engineering that really left them speechless were the awe-inspiring rope bridges , crafted and maintained by Inca communities with nothing but woven grass.
The vast Inca Empire was united by an incredible road network spanning over 25,000 miles (40,000 km). This impressive system traversed the harsh mountainous terrain of the Andes and ran along the coast, linking Ecuador in the north to Chile and Argentina in the south. It was a remarkable feat of engineering, designed to connect and sustain the expansive Inca civilization.
