Flakfortet, Sea fort at Saltholmrev, Denmark

Description

Flakfortet stands on an artificial island in the Øresund strait between Denmark and Sweden. The complex features thick concrete walls and gun emplacements that show the typical design of an early 20th century coastal defense installation.

History

Construction took place between 1910 and 1914 as part of Copenhagen's defense network. The fort lost its military function in 1968 when coastal defense strategies changed and it was deactivated.

Culture

The fortress now hosts classical music concerts and offers tours where visitors can learn about early 20th century military design and coastal defense tactics. You can see how soldiers once lived and worked in this isolated outpost.

Practical

The fort is only reachable by boat from Copenhagen harbors like Nyhavn, with a crossing time of around 40 minutes. Visit on dry days when the ground and walkways are safest for exploring.

Did you know?

The fort was built using reinforced concrete caissons sunk into the seafloor, an early example of this technology in Northern Europe. This innovation allowed builders to create a stable military structure where only water existed before.
