634,1
This is what's left of the 634 in N 132 today once part of
the CP for the "Festungkommandant" of St Nazaire.
But we had a peek in 1999. At three sides there is a covered
trench, which connects the entrance, emergency exit,
tobruk and a second tobruk.
This was the way to get in.
The original entrance is filled up.
