The last bits of Atlantikwall on the western coast can be found from Bayonne (the Adour estuary) to the French-Spanish border at St Jean de Luz.
Compared to the Arcachon area there's quite a density of batteries and bunkers to be found.
Unfortunately due to industrialisation, housing and tourism much has disappeared too.
The main sites in this area are the battery Adour-Nord with the famous 'Hochleitstand' "Barbara", the coastal battery Adour-Süd (totally reshaped
in 2008), the defences in and around Biarritz and the batteries of Socoa.
This part of the AOK 1 was Küstenverteidigungsabschnitt F and was manned by Abteilungen of the M.A.A. 286, H.K.A.R. 1182 and 1287, E-batterie 664
and 674 and the I.R. 36, 57 and 355. The many coastal batteries provide pictures of beaches and excellent views.
