Cerro Rico, also known as the "Rich Hill," is a mountain in Potosi, Bolivia that was once the largest silver mine in the world. The mountain, which is over 4,800 meters (15,700 feet) high, was discovered by the Spanish in the mid-16th century and quickly became a major source of wealth for the Spanish Empire.

The mines on Cerro Rico were worked by indigenous people and African slaves, and the conditions were brutal. Miners were often forced to work in unsafe conditions, and many died from accidents or from the toxic gases in the mines. The silver extracted from the mountain was used to fund the Spanish Empire and was traded throughout the world.

Today, Cerro Rico is still an active mine, although it is no longer the source of vast wealth that it once was. Many of the miners who work there today are still working in dangerous and difficult conditions, and the mountain has become a symbol of the ongoing struggles of the people of Potosi.

Despite its troubled history, Cerro Rico is also a popular tourist attraction, with many visitors coming to see the mountain and learn about its history. Visitors can take tours of the mines, learn about the mining process, and see the conditions that the miners still work in today.
