You can sleep 508 feet underground in an underground suite in historic Sala Silvermine, one of the world's best preserved mine. Here you will see dark winding galleries, vast caverns and magic lakes. During its heyday, production amounted to more than 3 tons of silver a year, and a total of more than 400 tons of silver and about 40,000 tons of lead were extracted – completely by hand!
