The Gironde-Nord area begins at Ile Oléron and ends at Les Fées. The region between Les Fées and Pointe de Suzac is called the Festung Gironde Nord. The designation of the strongpoints is "Gi" and it is all part of KVA E1.
We covered this part during a trip in the year 2000. Henk Adriaanse and team made a contribution during his trip in 2011.
