A small Wn on the inner edge of the northern side of Fécamp situated near the chapel is an R621 group shelter (we did not look for it) and a low long brick building unterstand. Possibly a living/kitchen/
mess/office type of building with two doors and five windows and its south side covered with an earth bank.
We did not look inside on our visit. Next the R621 and the yellow square is a defence position and probably is not in Fe07 but shown here.
