History
El Teniente mine operations began in the early 20th century, with the company town of Sewell founded in 1906 by the Braden Copper Company to house workers.
The town grew rapidly, reaching over 16,000 residents by 1960.
Ownership shifted to the Chilean government in the late 1960s and early 1970s, culminating in nationalization in 1971.
Following this, many residents were relocated to the valley below, connected by the Copper Highway.
Sewell's decline began with partial demolition of buildings in the 1980s, but preservation efforts halted destruction, leading to its designation as a National Monument in 1998 and UNESCO World Heritage Site in 2006.
