Sassnitz is a town on the Jasmund peninsula, Rügen Island, in the Federal State of Mecklenburg-Vorpommern, Germany. The population as of 2012 was 9,498.
It is a well-known seaside resort and port town, and is a gateway to the nearby Jasmund National Park with its unique chalk cliffs. The decommissioned British submarine HMS Otus was purchased by a German entrepreneur and towed to Sassnitz to be a floating museum. The Sassnitz area is most popular for its famous chalk rocks (Kreidefelsen), which inspired artists like Caspar David Friedrich.
