The Fortress of Kuelap was built and inhabited by the Chachapoyas between 1000 and 1400 AD. Built up in the high mountainous Peruvian jungle, it is one of the country’s most important archaeological complexes open to visitors, who never fail to be surprised when visiting for the first time. Surrounded by cliffs and precipices, it is like an unconquerable palace where the walls and circular houses are covered by the cloud forest which conceals many ceremonial sites and aqueducts.
