Take a short ferry ride to this fortress island in my Dutch hometown of IJmuiden. Forteiland is a fortified bunker complex located at the entrance of the north sea channel which connects Amsterdam to the North Sea.

My brother Hugo & Sterre joined me on this adventure. The fortress was a lot bigger than I initially expected, it has tunnels that stretch almost half a kilometer underneath the island.

The Forteiland museum managed to collect many artifacts from the Nazi era such as household products, Nazi uniforms and other items from Wold War II.
