Humberstone and Santa Laura Saltpeter Works
Tarapacá
Humberstone and Santa Laura Saltpeter Works are two former saltpeter refineries located in the Atacama Desert, northern Chile, recognized as UNESCO World Heritage Sites since 2005. These sites represent the pinnacle of the saltpeter mining boom in the late 19th and early 20th centuries, reflecting the industrial, social, and architectural legacy of the nitrate industry. Founded in 1872 under Peruvian administration, Humberstone and Santa Laura rapidly developed into bustling towns distinguished by British-style architecture. Humberstone became the most successful saltpeter works, especially after modernization with the Shanks extraction process in the early 20th century. The industry declined after the development of synthetic fertilizers, leading to abandonment by 1960. Restoration efforts have preserved key buildings such as Humberstone's theater, church, and company store, and Santa Laura's iconic chimney and processing plant. These sites provide a vivid glimpse into the lives of pampino workers and the industrial heritage of Chile’s nitrate era, set against the stark landscape of the Atacama Desert.

Historia
Established in 1872 when the area was under Peruvian control, the Santa Laura and La Palma (later Humberstone) saltpeter works quickly expanded, becoming industrial hubs with British architectural influence.
The Shanks extraction process was introduced between 1918 and 1920, improving productivity.
The Great Depression and the invention of synthetic ammonia fertilizers in the late 1920s caused the nitrate industry to collapse.
Both works were acquired by COSATAN in 1934 and renamed, with Humberstone becoming the leading site.
The decline continued, leading to abandonment in 1960.
The sites were declared national monuments in 1970 and later restored, culminating in UNESCO World Heritage designation in 2005 and removal from the endangered list in 2019.
