What Stichting Erfgoed Den Helder does

Stichting Erfgoed Den Helder is a Dutch non-profit foundation (stichting) established in 1989 that manages and develops a portfolio of military heritage assets in and around Den Helder, in the North Holland province of the Netherlands. The foundation holds ANBI (Algemeen Nut Beogende Instelling) status as a recognized public benefit institution and operates with a small team of approximately 7 employees. Its portfolio spans forts, bunkers, and the Willemsoord naval complex, covering Dutch military history from the Napoleonic era through the Second World War, including the Atlantic Wall fortifications.

The foundation's core offering is the preservation, restoration, and public presentation of these physical heritage sites. It operates visitor experiences such as the Atlantikwall Centrum, Fort Kijkduin, and the Fortwachterswoning overnight accommodation, alongside educational programming for schools and interactive experiences such as the Fortslag game. Real estate on the Willemsoord complex is partially rented out as a separate commercial stream. These activities form the product surface that translates physical heritage into accessible visitor and educational content.

The business model combines four revenue streams: government subsidies (municipal Den Helder, provincial authorities, and EU programs including LEADER and Waddenfonds), ticket and experience revenue from visitors, real estate rental income from portions of the Willemsoord complex, and donations. The foundation is structurally dependent on public-sector funding for its preservation mandate, with commercial activities serving as supplementary rather than primary revenue. Customer segments include leisure tourists, school groups, military history enthusiasts, and tenants of the Willemsoord commercial spaces.
