A seemingly indestructible bunker with monumental status is sliced open. The design thereby opens up the minuscule interior of one of NDW’s 700 bunkers, the insides of which are normally cut off from view completely. In addition, a long wooden boardwalk cuts through the extremely heavy construction. It leads visitors to a flooded area and to the footpaths of the adjacent natural reserve. The pier and the piles supporting it remind them that the water surrounding them is not caused by e.g. the removal of sand but rather is a shallow water plain characteristic of the inundations in times of war.
