Expedition to the Tuna Hästberg Mine

We invite you on an autumn diving trip to an extraordinary place.

In the Swedish village of Tuna Hästberg, there is a flooded mine where iron ore was mined for more than 600 years. It got closed in the mid-1950s. thanks to a group of enthusiasts, it is now a monument under the protection of the Swedish government. For more than 10 years, it has been open to the public and the flooded parts to divers, where in the crystal clear water (visibility up to 30 m), its secrets can be rediscovered.

Underwater, you will encounter an underground town where miners worked in multi-day shifts centuries ago. The mine equipment, personal items left by the miners and various wooden structures, bridges, cottages, dining rooms, shops, etc. have been preserved to this day.
