Middelgrundsfortet
From Wikipedia, the free encyclopedia
Middelgrundsfortet or Fort Middelgrund, known as Ungdomsøen (The Youth Island)[1][2] since 2015,[3] is a sea fort located on an artificial island in the Øresund between Copenhagen and Malmö. The fortress is constructed at a point where the seabed is 7 meters below the water surface, and at the northern meeting point of the straits Kongedybet and Hollænderdybet.
