Trekroner, Cees van RoedenThe forts Flakfortet, Middelgrundsfortet and Trekoner are small man-made islets located a few kilometres off the coast. The islets were constructed in the 19th century as part of Copenhagen's defence system, but today they are open to the public and popular goals for outings for everyone looking for a few hours on a "desert island".
