Discover the Defense of Willemstad

It was Willem van Oranje himself who ordered two polder villages to be turned into impregnable fortified cities: Willemstad and Klundert. Did the enemy come too close? Then, the surrounding area was flooded. The arrival of a ring of forts protected the fortified towns further, creating the Defense Line of Willemstad. This resulted in a unique defense line full of well-preserved secrets, divided among five forts.
