Most people who come to Oelsnitz come to see Schloss Voigtsberg, a most formidable castle that sits high on the mountainside. The oldest part of the Schloss is its donjon, or tower, that was built around the 1230’s; making it almost 800 years old. The castle has a museum. The Oelsnitz Carpet Museum at Voigtsberg Castle is dedicated to this frequently ‘trampled-on’ textile. Tied to the 130-year history of local machine and industrial carpet weaving, it provides information about the various carpet manufacturing techniques and shows, among other things, the variety of design on a ‘Road of the Best’. The castle’s actual treasury, however, is to be found in the historical vaults. It is there where the ‘Oelsnitz Minerals Vault’ displays a gorgeous collection of 400 minerals typically occurring in the Saxon Vogtland region.
