In to the mountain
The Old mine has a large underground cavern, Fagerlisalen, where the miners once worked. It is also appropriately known as the ‘Cathedral of labour and toil’. There, miners would have strived to earn their living by extracting the ore from the hard rock. This was done by fire-setting, which would have involved setting large fires close to the rock face. The resulting thermal stresses would have caused cracking. After the fires had died down and the smoke had been ventilated, the miners would broken up the loosened rock with picks. Pieces of rock containing ores would then have been carried up and out of the mine shaft, and new supplies of firewood taken down. Hence, over time, the mine gradually increased in size.
