14. Humberstone and Santa Laura, Chile
In the heart of the Atacama Desert, Humberstone and Santa Laura blossomed as bustling nitrate mining centers during the late 1800s and early 1900s. Their fortunes collapsed when synthetic fertilizers replaced natural nitrate, leading to swift abandonment. Today, the weathered machinery and empty structures stand as silent witnesses to the towns’ brief prosperity. Both sites are now recognized as UNESCO World Heritage sites, preserving the legacy of the nitrate boom era.
