Kastellet in Copenhagen was constructed in 1663 under King Frederik III, after the original fort on the site was compromised by a Swedish attack in 1658. It was partially rebuilt again in the nineteenth century when the distinctively star-shaped building, flanked by a moat, served as a prison.
During the Second World War, Kastellet was used as a base by German forces whilst they occupied Copenhagen.
Today, still in a great state of preservation, Kastellet is a military base. Its grounds have been turned into a park, which is open to the public, although there is no access to the inside of the fortification.
Just as empires rise and fall so do entry fees and opening hours! While we work as hard as we can to ensure the information provided here about Kastellet is as accurate as possible, the changing nature of certain elements mean we can't absolutely guarantee that these details won't become a thing of the past.
