The Chachapoya were an ancient civilization that lived in the cloud forests of the Andes in present-day Peru. Known as the "Warriors of the Clouds," they thrived between 800 and 1500 AD. The Chachapoya are famous for their unique burial practices, including cliffside tombs and mummification, which reflect their beliefs about life and death. Their society was characterized by impressive stone architecture, including the well-known site of Kuelap, a massive fortress that showcases their advanced engineering skills. The Chachapoya were eventually conquered by the Inca Empire, but their rich cultural heritage continues to intrigue historians and archaeologists today.
