S414 'Grand Bunker'
One mass of concrete.
Now leaving the guns and concentrating on the Fire Control Post. This was built for the battery and would also have taken on the four 30.5cm guns when they would have been commissioned.
Loading equipment into a new bunker.
Side view.
The steps to the entrance in the rear and the three observation levels looking out over the Loire estuary and covering the entry into the St Nazaire U-boat pens.

Light switch in recess.
I am not sure if its original but we often find the niches by the doors but never see what was in them..
Another type of switch
Close combat room.
A special mounting for the Mg34. This room is what may be called a guard room, any body entering and leaving may have signed in and out, also a spare cupboard for all sorts of things.

Why a French soldier and a Label machine gun should be defending the other CCD room. It could be a Fusil-Mitrailleur (FM) Model 1924-M29 with a side mounting magazine.
Fusil-Mitrailleur (FM).
Wash room (waschanstalt).
Model of the S414 showing how it would have looked as it was being built.
Later it was camouflaged with windows painted on and a false roof fitted. Look below.
As the S414 looked.
Oversized windows gave the impression that the bunker was smaller and was a house. It would be interesting to know if the camouflage worked?
Going up to the third and fourth level.
Thomas taking to bunker hunting with a passion and climbing up this ladder as if he had done it many times before.
Third level observation room.
This is a German stabilized torpedo guidance optics and would not have been used here, but an example of what may have been used here. .
Observation binoculars.
A lovely piece of equipment, needs cleaning but you can view through the lenses. One sailor would stand with the straps under his armpits and look through the eye pieces. Then another sailor would stand at 90degrees to the first and look through a matched pair of eye pieces and by adjusting knurled adjusters the enemy could be targeted.

The view.
Now our new bunker hunter advances to the upper layer.
The steps up to the fourth layer.
Looking into the range finder room of an M162a but is very much like the one in an S414.
Range finder room.
Held up with heavy steel jacks which tend to rust out, this one has some smaller extra ones added.
360degree observation room, cold and windy with no windows.

This could be the base of an original range finder.

A nice mix of naval officer and young woman radio operator, an Italian soldier, on the left an army radio man and right a Field Gendarme
The Italians had a submarine unit in Bordeaux and may have had a liaison officer here.
Wall painting.
A copy of a wall painting that was painted on a hotel wall in the area.
Shelf storage.
Gas mask tin holders and M45 tin helmets.
Model of the bunker.
This model shows the way the camouflage was painted on and an added roof.
Anti gas filters.
Two hand operated filter sets, a handle not unlike a cars starting handle attached and turned at a steady speed, air is sucked in from outside and filtered of gases (if used) or smoke. and the bunker will be over pressured so any leakage, gas could not enter the sealed areas of the bunker.

Store room.

Armoury.
Mg42 on a tripod, several rifles, 60mm mortar and some 60mm Panzerfausts.

Bunker Hunter One.

Concrete tetrahedral beach defences.
Now what it is?
Some form of beach defence, possibly a concrete case for an old shell that would have had a simple mechanism when activated the shell would explode.
