Kastellet
One of the best-preserved five-pointed star fortresses in Northern Europe, with red barracks, a windmill and a moat, just a few hundred meters from the Little Mermaid.
Begun in 1626 under Christian IV, it remains a military base today, but its ramparts and grounds are open to the public for walking and jogging. Visitors can see the long rows of red 17th-century barracks, a church, a windmill and walkways along the ramparts, with views over the moat and the harbor. Admission is free and it is open 06:00–22:00. The Little Mermaid statue lies just to the north, while to the south are the Gefion Fountain and St. Alban's Church, so the area is well suited to exploring all at once.
