Schwansen

Swania (, or "Svansø", meaning "swan island/peninsula") is a peninsula in Schleswig-Holstein, Germany, protruding into the Baltic Sea. It is located between the Eckernförde Bay to the south and the Schlei (English: Sly) inlet to the north.
The Danish dialect South Jutlandic was still spoken in Swania around 1780 (the last time in the villages near the Schlei). Denmark lost Swania following the Second Schleswig War in 1864.
Schwansen is the name of the former "Amt" ("collective municipality") Schwansen, which covered most of the peninsula. The seat of the "Amt" was in Damp.
