Fortresse Holland

Fortresse Holland Open-Air Museum is located on the unique grounds of the West-Slijk Front. This is not just a museum with display cases, but a historic defensive structure where you can literally walk through history. The museum focuses on the period from the 19th century to the Cold War. In the restored powder magazines, casemates, and barracks, you’ll discover how soldiers used to live and how the Hellevoetsluis fortress played a crucial role in defending the Dutch coast.
