The two villages on the coast, Audresselles and Ambleteuse are combined in one menu. Strongpoint "Heidelberg", nr 170, was built along the promenade of Audresselles:
Wn 202 is north of Ambleteuse and has a bunker with an unknown function and a nice tobruk.
Stützpunkt "Brachvogel" covered the small estuary of the river La Slack, which runs south of Ambleteuse into the sea.
More inland we visited Slack, Wn Drossel 1 and we continue the trip along the coast with Slack les Dunes.
