​​The anti-aircraft batteries were a powerful air defence system designed to repel attacking aircraft. With the exception of the battery on Vrijburgweg, all the others have been demolished during the war. However, this battery has also been severely damaged. Only two gun emplacements and a shelter bunker remain. Officially, it was known as the schwere Flak-Batterie Vlissingen-Nord.

When the area was flooded, the battery found itself in the water, protected only by a hastily constructed embankment. It was a vulnerable position, about which a naval officer remarked that the battery lay there like a shipwreck, an easy prey for aircraft.

Nevertheless, this battery remained active until the very last days, supporting German defences in West Zeelandic Flanders. On 28 October 1944, the battery was still involved in shooting down a Lancaster bomber.
