The village of Equihen-Plage to the south of Boulogne-sur-Mer boasts a fascinating mixture of bunker sites including positions for anti-aircraft guns, a radio guidance station, defensive batteries, and multiple strongpoints.
Stp266 Lupine was originally a barracks site for builders of nearby batteries (none of these buildings remain) with just two permanent structures – both ammunition storage bunkers – which are covered by gorse and the land is used for sheep and goat grazing so is not accessible.
This high-ground location saw three, 2cm anti-aircraft guns sited here.
