Orijärvi Mine

Orijärvi Mine is a copper mining complex located near Salo featuring multiple shafts and industrial structures that descend through various underground levels. The site displays extraction facilities and infrastructure that developed over centuries of operation.

The mine began in 1757 following copper ore discovery and grew into Finland's main copper source during its active years. Production expanded significantly during the Napoleonic Wars when copper became crucial for military and economic needs.

The site represents a connection between industrial labor and community life that shaped the region for generations. Local families were tied to the mine's rhythm, making it central to how people in this area lived and organized themselves.

Visitors can explore the mine through guided tours that explain the extraction methods and geological features. Wear sturdy shoes and stay alert on the underground pathways, as conditions can be damp and confined.

The abandoned shafts have filled with water to create an underground lake system descending hundreds of meters below ground. These subterranean waters mark where mining operations once extracted copper from the earth.
