The open air mining museum offers a long underground excursion in mines dating from the 17th century. Visitors will receive helmets, cloaks and lamps to use during the tour. It is also possible to have an English, German or Hungarian speaking guide if this is requested in advance. Another ancient mine open to the public (Slovak: "Glanzenberg") is even older. This mine, situated just under the center of the town, has attracted numerous famous visitors, from Emperor Joseph II to Prince Albert of Monaco.
