Sewell is one of the strangest and most atmospheric places within reach of Santiago. Founded in the early twentieth century by an American mining company at the foot of the El Teniente copper mine, the town was built on a steep slope in the Andes at a height of more than 2,000 metres. There was no flat land, so the builders raised timber houses on terraces linked by steps, and Sewell became known as the City of Stairs. At its peak thousands of people lived there, with schools, shops, a theatre, a hospital and a club, though the town never allowed cars. Today it has no permanent residents, and visits are on guided tours only. UNESCO inscribed Sewell on its World Heritage List in 2006, recognising it as an outstanding example of a company town that shows how an industrial settlement was created in a remote mountain setting. You walk its steep paths, see painted houses in red, green and blue, visit the museum in a former building and learn about the miners and families who lived and worked here. The setting is dramatic, with cloud often drifting between the peaks. A day trip from Santiago handles the long drive and the access rules, and gives a vivid view of how Chile’s copper economy grew.
How it works
Tours leave Santiago early, travel south for around two to two and a half hours and climb a winding mountain road to the site. A guide leads the visit through the town, and photography is generally allowed in public areas. Access depends on the mine’s rules and weather, so book ahead and confirm times.
What to expect
The walk includes many steps and slopes, and the air is cool and thin even in summer. Interiors and the museum are usually part of the tour, with displays of tools, photographs and everyday objects. Snow can close the site in winter, so ask about the season.
Making the most of it
Wear sturdy shoes and layers, carry a rain jacket and bring water. The site is not suitable for people with limited mobility because of the stairs. Take time to listen to the guide’s stories, as the human history is what makes Sewell memorable.
