 The Gummanz Chalk Museum ("Kreidemuseum Gummanz"), the only chalk museum in Europe, lies not far from Sassnitz near Sagard on the terrain of an old chalk pit, worked from 1855 to 1962, and uses an open-air area with original implements as well as photographic and textual information boards, that describe the geological relationships, the mining and working of chalk on Rügen.In summer there is a regular briefing on archaeological discoveries for fossil collectors.The "glass station" ("Glasbahnhof") has lost its function as a result of the expansion of the new Sassnitz Ferry Port and today houses an exhibition and events hall as well as the Museum for Underwaterarchaeology ("Museum für Unterwasserarchäologie").
