The “Mineraliengewölbe Oelsnitz”, a collection of valuable minerals from the Saxon Vogtland, is situated in the historical vaulted cellars of the castle.
In specially designed display cabinets, treasures such as barite from Zobes, wavellite from Schloditz or the world famous fluorite from Schönbrunn can be marvelled at. The location where each mineral was found is indicated respectively.
The venerable castle was deliberately chosen as the exhibition venue, as Schloss Voigtsberg served as both as the electoral seat and the mining authority between the 17th and 19th century. From 1674 on, it served as the mining authority of the elector and the high principality for almost the entire Saxon Vogtland region.
