Río Abiseo

Site History and Significance

A Constellation of Understudied Archeological Sites

Peru’s Río Abiseo National Park is famous for both its natural and its archeological richness, which resulted in its designation as a Mixed World Heritage Site in 1990. The grounds cover an area of roughly 274,520 hectares of mountain forests and are also home to the remains of numerous buildings from the Chachapoyas civilization. These ancient sites have yet to be fully explored by scholars, as the park is extremely difficult to reach—requiring days of donkey trekking through rugged mountain terrain. The archaeological sites indicate a significant level of human occupation, which dates back to 3,000 BC, however the most monumental sites and productive areas are concentrated approximately circa. 1000 – 1470 AC associated with the Chachapoya culture until the Inca conquest. Since 1985, 36 archaeological sites have been found, including rock shelters, roads, storage structures, platforms, agricultural terraces, burial sites, and domestic and ceremonial complexes.

Stabilizing and Studying Chachapoyas Heritage

The park’s remote location means that these archeological remains have been saved from interference and possible damage—but it also means that they have not received much in the way of care or maintenance. As a result, many areas are now overgrown by trees and vines, weakening the buildings and imperiling their continued survival.

WMF has proposed a project for Río Abiseo with the goal of better understanding the site and stabilizing the structures most in need of help. The intervention will focus on Gran Pajatén and Los Pinchudos, where the WMF team will concentrate on documentation, assessment, and conservation where needed. WMF will work closely with local communities in the departments of La Libertad and San Martín to evaluate their needs and desires within the national park while setting up standards to protect the natural environment in an archaeological context.
