Fortress Triangle for business
Destinations
Castle, fortress and state prison where the Maas and Waal meet
Where the rivers Maas and Waal meet and three provinces touch, stands the most famous castle in the Netherlands. Knight’s castle, toll castle, the state prison of Hugo Grotius and a military fort of the Dutch Water Line: Loevestein has more stories than a day can hold. For groups, the castle is a backdrop you could not invent.
