- Gun positions: The armored emplacements show how artillery once covered the harbor entrance.
- German bunkers: Concrete additions from the Second World War, a clear contrast with the older brick.
- Ship watching: Freighters, ferries and pilot boats pass close by on their way to the canal and the Port of Amsterdam.
- Guided tours: When offered, guides explain the engineering of building an island in open water and its role in the defense line.
- Harbor views: From the walls you can see the IJmuiden locks, the piers and the North Sea beyond.
