NHW-Fort Spion

Fort Spion is a fortification complex near the Loosdrechtse lakes, constructed with distinctive earth walls and water channels as defensive features. The structure follows the geometric design typical of water-based forts, with interconnected defense zones and open parade grounds.

The fort was built during the early and mid-1800s as part of a wider defense system protecting Dutch territories. It remained operational until the middle of the twentieth century, when such waterline fortifications became obsolete.

The fort reflects Dutch defensive strategy through its design of earth walls and water channels that were common along the New Dutch Waterline. Visitors walking through it can see how military engineers shaped the landscape to create protection through water rather than stone.

The site can be explored on foot, with paths leading across the fort grounds and along the earthen ramparts. Visitors wanting to stay longer can use camping facilities on the grounds or book accommodation in the small residential building.

The fort allows visitors to camp directly within its historical boundaries, offering a rare experience of sleeping surrounded by nineteenth-century military architecture. This creates an unusual connection between modern outdoor recreation and preserved defense structures.
