Kuelap is an ancient fortress located in the northern highlands of Peru. Built by the Chachapoya civilization around the 6th century, it sits on a mountaintop at an elevation of approximately 3,000 meters. The site features massive stone walls, some reaching up to 20 meters in height, and contains over 400 structures, including residential buildings and ceremonial spaces. The fortress is often referred to as the "Machu Picchu of the North" due to its impressive architecture and historical significance. Kuelap was largely abandoned by the 16th century, but it has gained recognition in recent years as a key archaeological site, attracting visitors interested in Inca history and culture.
