Po 39b has two casemates 669 which are overgrown and in ruins. They can be found south east of Saint Adrien. Main target was the beach at Kermouster. 15.5 cm s.F.H 414 (f) guns were manned by 10./A.R. 266.
Number one is almost unreachable.
This roof is fully collapsed.
It looks a little bit like a 669.
Nature takes over and tries to hide the ruins.
