Karlslunde is a suburb 25 km (16 mi) south-west of central Copenhagen, Denmark. The suburb is a part of Greve municipality. Karlslunde is generally divided into Karlslunde Landsby and Karlslunde Strand split by Karlslunde Landevej (Taastrupvejen). The suburb is connected with the S-train network lines A and E.
The city has a fairly rich history, since the Danish king Svend Grathe in 1153 fought an important battle against the Wends in Karlslunde, in which he defeated them. Karlslunde was also part of Tunestillingen which was a defensive line to protect Copenhagen against a possible attack from the Germans under World War I. Mosede Fort (also in Karlslunde) is an old fort which was a key part of this defensive line. Mosede Fort also has a very interesting interactive museum where you can learn more about Tunestillingen and the central role Karlslunde played in it.
