Copenhagen Citadel

Local nameKastellet
LocationCopenhagen, Denmark

The impressive fortress is one of the best-preserved fortifications in Europe. It was built in 1663 as a fortress and since the 19th century it was used as a prison. It is located close to the popular Little Mermaid statue.

Even though the buildings inside the Citadel are used as military barracks and offices, now that the time of wars is over, it serves mainly as a pleasant park where you can enjoy a walk on the ramparts.
