Fortress Triangle for business
Destinations
Biesbosch Line
Woudrichem, Fort Altena and the Biesbosch: nature and defence line in one
Between the fortress town of Woudrichem and the national park lies the Biesbosch Line: forts, sluices and inundation fields in the middle of tidal nature. Here the story of defending with water becomes literal: you sail right through it. For groups that want to slow down, or get on a bike, this is the green heart of the triangle.
