Discover Fort Harssens: an underground armored fort full of stories

Step into history with a tour of Fort Harssens. This armored fort, dating from 1880, is tucked away beneath the Port Office at Den Helder and is normally closed to the public. Guides will lead you through dark corridors, where the atmosphere of 1900 still lingers.

Dive into the past

The fort was built as part of Stelling Den Helder (Foreign Defence Line Den Helder). You walk through empty spaces and narrow corridors where Dutch soldiers, the German occupying forces, and later the Royal Netherlands Navy once stayed. Nothing here has been furnished: everything remains as it was.

Watch your steps

The route is underground and narrow or dark in some places. Steps and uneven surfaces make the fort less suitable for wheelchair users or those with limited mobility. Children are only permitted when accompanied by an adult.

Limited access

You may only enter the fort after registering at least five days in advance. Your name and date of birth are required due to the military location. There is room for 25 participants per tour. Register via the website. Full = Full.
