Middelgrundsfortet (), 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.

History

Christian IX's government constructed the fort between 1890–94 to serve as a part of Copenhagen's coastal fortifications, partly using material excavated from Frihavnen. It is one of three artificial islands that were created to defend the entrance to Copenhagen's harbour. The other two are Flakfortet and Trekroner Fort.

Middelgrundsfortet was the largest sea fort in the world, and is still the largest man-made island without abutment, with an area, including wave breakers, of approximately 70 000 m2; the buildings total approximately 15 000 m2. A HAWK battery was placed on the island in the 1950s. The fort remained an active military installation until 1984; in 2002 it was sold to a private investor.

The camp can accommodate over 650 outdoor, and 40 indoor, sleeping guests. It was officially opened in August 2019 by its patron Princess Benedikte. 10,000 people had visited the camp.

The KUNE music festival is hosted at the camp. A youth summit, "Young Europe Cares", was hosted by youth activist group Young Europe Is Voting/Youth4Europe at the Ungdomsøen in May 2019.
