Fort Harssens

Nineteenth-century ring fort protecting the landward approaches to the naval base

Fort Harssens is a well-preserved ring fort built in the 1840s and 1850s as part of the defensive perimeter around Den Helder's naval base. The earthwork and masonry construction follows the classic pattern of the era — a circular profile with ditches designed to deflect cannon fire and a central redoubt for the garrison. The fort is part of the broader Fortifications of Den Helder, a set of linked defences that protected the naval base from both sea and land.

The fort is accessible on foot and makes a good destination if you are cycling or walking around the perimeter of the city. The combination of nineteenth-century masonry and later German Second World War additions gives a layered sense of Den Helder's military history. Signs interpret the site in Dutch and English.

A story
Fort Harssens was one of a chain of defences protecting the naval base from landward attack. During the Second World War, German forces occupied and expanded the fortifications, adding concrete bunkers to the older nineteenth-century earthworks — layers of military history compressed into a single site on the edge of the city.
