Kuelap
900 CE – 1470 CE
A colossal stone fortress-city perched on a limestone ridge 3,000 metres above the Utcubamba Valley in the Peruvian Andes — built by the Chachapoya, the "Warriors of the Clouds," between roughly 900 and 1470 CE. Enclosed by walls up to 19 metres tall and packed with over 400 circular stone houses, Kuelap is often called the "Machu Picchu of the North" for its scale, preservation, and dramatic mountaintop setting — yet it predates Machu Picchu by centuries and was never an Inca creation.
