Blåberg
The mountain Blåberg is situated near the Øvre Årdal town in Norway. It is a well-known tourist hiking spot, known for its 18th-century mines.
Blåberg saw centuries of copper mining. In the 18th century rich sources of copper were found, and mining began in the valleys and mountains across the Årdalsfjord part of the Sognefjord.
Blåberg was called the Mine Mountain.
