During the open monuments day om September 11th the museum is open (and free) for everyone. On Sunday the cannons will roar at 14 and 15 hours. Our captain will explain (in Dutch) and after that the cannonniers will work hard. All for the Netherlands and Orange!
The Dutch Fortress Museum will host the Waterline Walking Tour on 21 May 2022. The museum is closed for museum visits on this day.
