Discover more about Humberstone and Santa Laura Saltpeter Works

Humberstone and Santa Laura Saltpeter Works, located in the arid Atacama Desert, stand as a testament to Chile's vibrant, yet bygone, saltpeter mining industry. From the 1870s to the 1950s, these sites were at the heart of the 'saltpeter fever,' driven by global demand for sodium nitrate, a key fertilizer. Designated a UNESCO World Heritage Site in 2005, the works offer a unique window into the lives of the 'pampinos,' the workers from Chile, Peru, and Bolivia who lived in these isolated company towns. They developed a unique communal culture, evident in their language, creativity, and fight for social justice. A visit to Humberstone and Santa Laura is an immersive experience. Humberstone, the larger of the two, features better-preserved residential and service areas, offering a glimpse into the daily lives of its former inhabitants. Explore the town's remnants, from homes to the theater and swimming pool, and gain insight into the challenges and triumphs of life in this remote desert community. Santa Laura showcases the industrial side of saltpeter production, with better-conserved industrial installations, including leaching sheds and machinery. Both sites were abandoned in 1960, marking the end of an era. Today, they stand as ghost towns, offering a poignant reminder of Chile's industrial heritage. Allow at least 3 hours to explore this expansive site.
