The Trekroner Fort is just a stone's throw from Copenhagen and this fact makes it a great spot for a Sunday trip.
The sea fort stands on one of three artificial island that were created to defend the entrance to Copenhagen's harbour. It was built in 18th century and was part of the fortifications of Copenhagen until after the World War I.
There are no soldiers nowadays. :) The main building is quiet dilapidated, yet it invites to exploring. And the view from the top of the building is just amazing!
The island is easily accessible by boat. The company Canal Tours Copenhagen offers a 50-minute tour from May to October and their boats are leaving from Nyhavn every hour. Don't forget your swimming suits and picnic basket! :)
