Gran Saposoa

A series of ruins in the Andean cloud forests of Peru's Amazonas region, brought to international attention by explorer Gene Savoy in 1999. The site complex covers an estimated 25 square miles and includes mountaintop citadels with hundreds of circular stone houses, cliffside tombs, agricultural terraces, and stone watchtowers. Some ruins date to the 7th century, making them among the oldest known Chachapoyas structures. Scholars dispute Savoy's claims, noting the sites were previously located by Keith Muscutt and Inge Schjellerup in the mid-1990s.
