“…The ditch is not visible on post WWII French air reconnaissance images. Therefore, it is not possible to assume that it could have had the functions of either hosting and protecting one or more shacks for personnel lodgement as those at Cap Fréhel (Tomezzoli & Moser, 2021), Qu 500 and Qu 13 at the Pointe du Raz (Tomezzoli, 2021), on the Menez Hom (Tomezzoli, 2017a) and at Flescou (Tomezzoli, 2022) or be a pool as those at Murs Érigné (Tomezzoli, 2016) and at the Domaine de Pignerolle (Tomezzoli, 2019) for providing relax to the personnel in service and water in case of fire to the devices of the Stp. Mr Clochon is of the opinion that it was excavated after the WWII for providing water in case of fire at the buildings of the after WWII Radio Conquet components.…”
