Cerro Rico Cerro Rico (Spanish for "rich mountain"), Cerro Potosí[1] ("Potosí mountain") or Sumaq Urqu[2] (Quechua sumaq beautiful, good, pleasant, urqu mountain,[3] "beautiful (good or pleasant) mountain") is a mountain in the Andes near the Bolivian city of Potosí. Cerro Rico was famous for providing vast quantities of silver for Spain during the period of the New World Spanish Empire. The mountain, which is popularly conceived of as being "made of" silver ore, caused the city of Potosí to become one of the largest cities in the New World.[4]
