WW2 Emergency exit Bunker at Dunkirk

Part of Batterie de Leffrinckoucke
Climbed in via bunkers emergency exit. Sorry quality is not good. My first explores and video of such. The steps were hanging in the air and would have led to another entrance. Bunker was half filled with sand. My knees have seen better days and too many pies...... Pls sub/like so I can try and earn a pie out of this.
