Step into a city where history and the sea have left their mark.

Discover resilient heritage in Den Helder

On Saturday 12 and Sunday 13 September 2026, Den Helder opens doors that normally remain closed. During Open Monument Day Den Helder 2026 you will discover special buildings, hidden places, and stories from different eras. The national theme this year is Resilient Heritage – In Times of Uncertainty. A theme that becomes particularly palpable and visible in this maritime city.

Discover how Den Helder changed time and again

A city by the sea learns to live with change

Den Helder is a city that has had to constantly adapt to change throughout the centuries. Its location by the sea, the navy, wars, and new functions have left their mark on buildings and the landscape. Some places retained their original function, while others were given a completely new life. During Open Monument Day, you will discover how the past is still part of the city of today.

Classic cars, history, and a special drive along the dike.

Heritage in motion

On Sunday, September 13, the past literally comes to life during the Historic Tour. Starting at 11:00 AM, classic cars and special vehicles will depart from Willemsoord for a festive route through Den Helder. This year, they will also drive along the dike, with the sea as a unique backdrop. Around 12:30 PM, the vehicles will return to Willemsoord, where you can view a number of special examples up close and soak up the atmosphere.

Behind doors, walls, and monuments, stories await.

Look beyond the facade

Behind many monuments lies a story that you cannot see from the street. Step inside places where different rules normally apply or whose doors usually remain closed. Discover stories about people who worked, lived, met each other, or sought protection there. In this way, history becomes not a collection of dates, but something you can see, hear, and experience.

Follow the traces of the sea, shipping, and navy through the past of Den Helder.

Experience a maritime city full of stories

The sea and the navy have shaped Den Helder and still give the city its own character. This is reflected in the nautical heritage, the former fortifications, and places where shipping and maritime history remain tangible. But Open Monument Day also reveals other sides of Den Helder, from architecture and faith to art and meeting places. It is precisely this variety that makes it interesting to combine multiple locations.

From Julianadorp through the dunes to Huisduinen, with stories along the way.

On Saturday, September 12, after the official opening, hop on your bike for a free historical tour through Den Helder. You depart at 10:30 AM from the Ontmoetingskerk in Julianadorp and cycle through the dunes towards the Huisduinerkerkje.
