Opening

There are also openings this year and of course we would like to let you know. Enthusiastic volunteers make it possible to open our doors more often and to share the special military heritage of Hellevoetsluis with the public.

Check our agenda for the openings.

Volunteers will be happy to tell you how the Hellevoet fortress has developed over time to defend the all-important naval port. We have panels for this, each of which shows an important period. On the basis of old maps you can see and hear how that development went.

Admission is free.

When are we open?
The days that we are open can be found on our page with the calendar. We would like to open more often, but then we need more volunteers, will you help?

What else is there to see?
You can also take a look at our soldiers' room. Perhaps you can still smell the sweat of the gunners there. We can also show you the ingenious water drainage system there.
Ask a volunteer for a look. The soldiers' room cannot be entered directly from our visitors' room.

You can also briefly listen to the story about our great pride, the 24 cm Yser.
This cannon now stands proudly on the shore and looks menacingly over the water. At that time the largest rear loader in the Dutch army.
Did you know that 13 of them stood on the Hellevoetse fortress?
Volunteers will then walk with you for a while.

Children can dress up as a real soldier.
Always nice for a photo!
