Since 1975, the Barbarastollen, a reconstructed part of the mine, has been used by the Federal Office for Civil Protection and Emergency Aid as a storage facility for Germany's archived materials. The tunnel is Europe's largest long-term archive. Mining museum The research team Steiber, founded in 1976, cleared and surveyed several old parts of the mine. A part of an old ore mine has been transformed into a museum that has been open to the public since 1997.
