In half a century of activity, Sewell went from being a copper mining camp to a full-blown city. Founded in 1906, just over 50 years ago it was inhabited by 15,000 people and had become a model place with a cinema, the best hospital in the region, and a planned geometrical layout for its houses.
During the last third of the twentieth century Sewell was uninhabited, until in August 1998 when the former camp was declared a National Monument in the «Typical and Scenic Area of the Libertador O’Higgins region.
It is known as the city of staircases, and those staircases are high, as the town is located 2,200 meters above sea level. Its main characteristic speaks with eloquence: it is the largest underground copper mine in the world.
The international recognition of Sewell’s superior attraction came in 2006, when Unesco declared it a World Heritage Site. For visits, it is recommended that you get in touch with one of the authorized companies listed on the website.
