At first called KV Gruppe Loire, later on promoted to Festung Saint Nazaire.
In this area many bunkers remain and in some cases complete with armoured parts,
such as plates and cupolas. A few inlandbatteries were built and so the
according bunkers for observation.
The harbour is worth the while because of the U-boatbunker (UBB) and the lockbunker
with the massive 40P8 Sechschartenturm on top.
The firecontrol bunkers with towers (type Fl 241 and Fl 250) for the AA-batteries
are typical for this Festung.
We spend in total three full weeks in these area and we are certain to have
missed other beauties. (1999 and 2002)
The strongpoints have the designation "N", or "Nz", of which N 57, the inlandbattery "Heinrich", remains our favorite. Many additional pictures were made by Henk Adriaanse in 2005.
