Eckernförde

Eckernförde is a German town in Schleswig-Holstein, Kreis Rendsburg-Eckernförde, on the coast of the Baltic Sea approximately 30 km northwest of Kiel. The population is about 23,000. Eckernförde is a popular tourist destination in northern Germany.
The name of Eckernförde is of mixed origin, but derived from the name of a Danish castle formerly located near the current town, which is also reflected in the name of the town district of Borby. This fortification is listed in the 13th century Liber Census Daniæ as Ykærnæburgh. In 1441, the town used an official seal listing its name as Eherneborgh. The first syllable corresponds to the modern Danish word "egern" meaning squirrel while "-förde" is Low German meaning fjord. The -förde ending is documented in Latinized form on two official seals used by the town in the 1602 and 1624. The etymology of the town's name is reflected in the presence of a squirrel in the town's coat of arms, a feature first documented by the 1441 seal.
