Cultural Heritage Site in Danger: Chili

Date of Danger Inscription: 2005
Province: Iquique
Humberstone and Santa Laura works contain over 200 former saltpeter works where workers from Chile, Peru and Bolivia lived in company towns and forged a distinctive communal pampinos culture. That culture is manifest in their rich language, creativity, and solidarity, and, above all, in their pioneering struggle for social justice, which had a profound impact on social history. Situated in the remote Pampas, one of the driest deserts on Earth, thousands of pampinos lived and worked in this hostile environment for over 60 years, from 1880, to process the largest deposit of saltpeter in the world, producing the fertilizer sodium nitrate that was to transform agricultural lands in North and South America, and in Europe, and produce great wealth for Chile. Because of the vulnerability of the structures and the impact of a recent earthquake, the site was also placed on the List of World Heritage in Danger to help mobilize resources for its conservation.
Threats to the Site:
The main issue to be highlighted is the extremely fragile nature of the buildings. As with most mining buildings, they were constructed using local materials and lightweight construction that functioned with regular maintenance and could be altered in response to changed circumstances.
The greatest threat is from looters searching for re-usable materials. During the time when the works were closed and still in private hands much was lost. Looters look for all sorts of memorabilia on the sites such as timber, bottles, coins and tokens. Although looting has dwindled, the Douglas Fir is much prized and, as it is now nationally protected in the USA, prices for it have risen. Timber was stolen from the Santa Laura Leaching plant in 1999.
Although the site is a virtually rain-free desert, windborne salt from the coast has an impact on the metal sheeting causing corrosion. Wind has also affected the wooden structures: those painted have been given a protective mineral coating by the salty wind whereas those unpainted have been eroded by the wind. |
