Moved here from public as it gave away a bit too much. A bit itchy on the trigger finger, I'm so excited and I just can't hide it.
Your bog standard huge Maginot Line fortress, empty for a very long time, untouched by war in both 1940 and 1944. A bit rotten but almost unvisited.
One of the retractable turrets as seen above ground
Some of the underground munition trains
Coleman stoves = awesome
Sign for the control box of a munition hoist. Massive beasts, with dedicated overhead pulley systems to carry entire closets of shells from the trains, straight into the lifts and several floors up to the combat bunkers
Aforementioned overhead hoist - these are entire networks, going dozens and dozens of meters through multiple magazine rooms
Interior of a twin rapid-fire 75mm artillery turret (what's underneath the mushroomy thing in the first pic). Below the breeches you can see the hoppers for empty shell casings. A screw ascender would bring new ammo up to the guns at a rapid rate; after firing, the brass would drop into these receivers from where it would take a long, spiraling slide about 50m down to waiting carrying bins hooked to the pulley system, which in turn would bring the empty cases to the ammo trains.
Air filtration system, one of many
A split in the underground train network, branching off the main line to one of the heavy combat positions
A workbench in one of the repair shops
Mount for a heavy artillery turret
Typical crew quarters
One of the tunnels
Also, OT, your name came up.
