Discover the Sani 638 Hospital Bunker during Open Monument Days.

Security in wartime: a unique piece of history

The sanibunker in Den Helder was built in the winter of 1942-1943. This medical bunker played a crucial role in the care of the wounded during the Second World War.

Professional care in a strategic location

A complete operating room was located in the sanibunker. Here, wounded soldiers were stabilized before being transported further inland. This offered a better chance of survival and relief for the front.

Compact, but effectively laid out

The bunker was under the command of the Kriegsmarine. One doctor and four nurses worked there. They could simultaneously care for ten lightly wounded and ten seriously wounded. An impressive achievement given the limited space.

Discover a rare preserved bunker

The Sanibunker can still be visited today. A visit offers you a unique insight into the medical side of the war. Not a museum full of ideals, but a realistic picture of care under extreme circumstances.

You know how to do it. At least, that's what you think. It should happen automatically. That's the story.

Event  Music
Roxeanne Hazes is homesick… for the theater. After an initial series of theater shows in 2025, she returns this autumn with a new album and a new show, '…met heimwee' (…with homesickness). It is the overarching theme of her upcoming third studio album. Homesickness for a home, or perhaps anything but. Homesickness for people, places, tastes, smells… and so much more. It has become a warm and hopeful album, yet with her typical melancholy and evocative lyrics. The first single, 'Chaos Gedoofd' (Chaos Extinguished), was released recently.
