17 Incredible Places That May Disappear Soon
Cerro Rico, Bolivia
Located near the city of Potosí, Cerro Rico (or Rich Hill) was once an important source of silver for the Spanish empire.
However, nearly 500 years of uncontrolled mining has resulted in the mountain becoming porous and unstable. In 2011, its famed peak was reported to be at the risk of collapsing and efforts were carried out to fill up a crater with ultra-light cement.
Also called the “mountain that eats men,” Cerro Rico was added to UNESCO’s List of World Heritage in Danger in 2014.
