This museum complex offers an overview of the history of tin mining at Altenberg from its beginnings around 1440 to the closure of the mine in 1991. On an underground guided tour of the two-hundred-year-old “Neubeschert-Glück-Stollen” (“Neubeschert-Glück” tunnel), visitors are able to see the methods and equipment that were used in mining the ore. In the historical tin washery, machinery that is still in working order is used to demonstrate how the ore was processed. This ore washery dates from the sixteenth century and is thought to be the only one of its kind in Europe. In the outdoor areas of the museum, the rule is – very unusually –: feel free to touch. A selection of mining equipment items illustrates ore-mining techniques employed at Altenberg. The mining history trail, which crosses the German-Czech border, connects sites and buildings of historical interest on both sides; still in their original locations, they reflect the variety and the history of this mining region.
