Mining at Kleva began in 1691 following the discovery of copper ore by a local farmer.
The mine was once one of the largest copper producers in the region during the 18th century.
A major fire in the underground tunnels occurred in the late 18th century, significantly damaging operations.
The mine features a large, naturally formed underground lake within its lower levels.
The temperature inside the mine remains constant at approximately 4-8 degrees Celsius year-round regardless of outside weather.
Mining activity officially ceased at the location in the 1920s.
Geologists often visit the site to study the unique mineral formations present in the rock walls.
The site is often used for events like the 'Gruvrock' music festival due to the unique acoustics of the mine chambers.
Kleva Mine is a historical copper mine located in the Småland region of Sweden, with mining activities dating back to the late 17th century. The site offers guided underground tours through a network of 18th-century shafts and galleries. Visitors can explore the cavernous underground rooms, which remain cool throughout the year. The mine was primarily used for copper extraction but also produced iron, cobalt, and nickel over its operational history. Above ground, the site features nature trails and remnants of historical mining infrastructure. It is situated in a forested landscape, offering a look into the labor-intensive industrial history of the Swedish mining industry.
