Abandoned German bunker below the surface in Trondheim (Lade) Norway. Possibly a multipurpose bunker which includes an air raid shelter. Close to the military headquarters for Lade airport. Part of the fun is finding these bunker yourself, but Lade should be a good enough hint. Seems like the electricity has been cabled in the tunnel ceiling. Water drainage in corridors and rooms, but does not seem to have an exit from the bunker.
