The defence work near Maarsseveen is one of the last ‘forts’ of the New Dutch Waterline, built in 1881 to close off access to the Maarsseveense Vaart. It housed a garrison of 80 men. Only the bomb-proof barracks remain; the earthen ramparts and the wooden outbuilding have disappeared over the years. Separate from the defence work, an older guardhouse also still stands.
