Werk aan de Waalse Wetering

This defence work was built in 1875–1878 and comprises a bomb-proof outbuilding and a guardhouse.

In emergencies, it could harbour as many as 95 men.

The fort is freely accessible and boasts uninterrupted views of the island of Schalkwijk. The Verdronken Bos (drowned forest), where a wooden walkway takes you across the water, is a short walk away.
