Humberstone, Chile was a booming town from the 1920s until the early ‘40s, enjoying the wealth and prosperity that came from mining and processing nitrate, also known as saltpeter. Once synthetic saltpeter was invented, the town began to decline and experienced a slow outpouring of residents until it finally lay empty in 1961. Since then, the blowing sand from surrounding deserts has made its way into the remaining buildings, which still house machinery and furniture. The town has been named a World Heritage Site and will likely be preserved as a historical monument.
