Eckernförde (Egernførde, sometimes also Egernfjord, Eckernför, sometimes also Eckernföör) (ɛkɐnˈføːɐ̯də) is a German town in Schleswig-Holstein, Kreis Rendsburg-Eckernförde, on the coast of the Baltic Sea approximately 30 km north-west 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 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. In 1197 Eckernförde was mentioned for the first time. Eckernförde was mentioned in the year 1302 for the first time explicitly as a city, but in 1288 the inhabitants were already called oppidani (city citizen). In 1628 it was taken by Christian IV of Denmark from the troops of the Holy Roman Empire. During the First War of Schleswig two Danish ships, the Christian VIII and the frigate tried to land in Eckernförde in April 1849. They were cannonaded from the shore. The Christian VIII exploded, while the Gefion surrendered and was captured. Theodor Preusser, the commander in chief of the southern troops, died while rescuing Danish troops from the Christian VIII. On November 13 the 1872 Baltic Sea flood hit the coast of the Baltic Sea from Denmark to Pomerania. Of all the German coastal settlements, Eckernförde was most heavily damaged due to its location on Eckernförde Bay which is wide open to the north-east.
