The zinc mines in Allmannajuvet in Sauda, Ryfylke were in operation from 1881 to 1899. The mining operations brought life to the village with as many as 168 employees and the export of ore on ships heading abroad. The operation was a forerunner of subsequent hydroelectric development and industrialisation in Sauda in Ryfylke.
As part of the establishment of the National Tourist Route Ryfylke, Swiss architect Peter Zumthor designed new facilities to be built at Allmannajuvet gorge: an exhibition gallery to show the history of the mines in a striking new way, a café and service facility, and parking for visitors. In order to reach the entrance of the mine, a spectacular road was constructed along the wild river. The new facilities will be completed and open in 2016. A new trail into the mines is planned for 2017.
