Sacha-p-qulla

The Chachapoya inhabited the eastern Andean slopes around the Utcubamba River in northern Peru. Their strongholds included Kuelap, a walled ridge citadel enclosing hundreds of circular stone houses.

In the 1470s Topa Inca Yupanqui fought to conquer their hill forts; deportations and revolts continued under Huayna Capac. Many Chachapoya sided with the Spanish invaders, who founded the town of Chachapoyas in 1538. Kuelap was abandoned in 1570.
