Denmark · 19th century
Middelgrundsfortet (lit. 'Fort Middle Ground'), known as Ungdomsøen (The Youth Island) since 2015, 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 at the northern meeting point of the straits Kongedybet and Hollænderdybet. Ferries connect Middelgrundsfortet with Langelinie, Copenhagen.
The fort was constructed in the 1890s as a military instalment, and had an active military presence until 1984. The island was sold by the state to a private investor in 2002 and was transformed into a hotel, with 200 rooms linked by 2 miles of corridors. In 2015, the island was jointly purchased by two scout organisations and is now used as a camp for children and young people as Ungdomsøen.
