Threats to the Site (1986)
The vast and fragile site of Chan Chan was inscribed on the List of World Heritage in Danger in 1986, the same year it was inscribed on the World Heritage List.
Its adobe, or earthen, structures are quickly damaged by natural erosion as they become exposed to air and rain and they require continuous conservation efforts and substantial ancillary measures.
The Committee recommended, therefore, that appropriate measures be taken for the conservation, restoration and management of the site, that excavation work be halted unless accompanied by appropriate conservation measures and that all possible steps be taken to control plundering of the site.
