On 9 June, two unique WWII bunkers in the small town of Driehuis, North Holland will be open to the public for one day only. According to Ruud Pols of the Bunkermuseum in IJmuiden, North Holland, this will be the first time these bunkers will actually be opened since the end of the war. Both bunkers are part of the Festung IJmuiden, one of the most important strategic defenses of the German Atlantic Wall. In fact, they’ll be open on National Bunker Day (Bunkerdag).

Pols also has no clue what they’ll find. Will it have been frozen in time or did someone already visit it that they don’t know about? No less than 2300 bunkers have been built in and around IJmuiden, a Dutch port city, and when taking a train and looking out the window in that area, you see cows grazing around the bunkers like it’s a normal sight.
