This large bunker is located deep underground. To reach it, visitors must descend a steep staircase. A chair lift has been built especially for disabled visitors. The bunker, a type Küver 431 Notstrom Bunker for 70 KVA, was equipped with an emergency power supply. It is a rare type; only two were ever built in the Netherlands, one on Terschelling and one on Schiermonnikoog.
The bunker is being used as an exhibition space for the first time. You can view the photos in the Terschelling Vrij exhibition that was organised as part of the V-fonds theme year 75 years of Liberation.
The photo shows the entrance to the bunker, which was specially built to protect the stairs and chairlift.
