Widerstandsnest 157 – Marine Seezielbatterie ‘Zuidzand’ Just south of Zandvoort, the Zuidzand battery was reported ready for combat around June 1942. The battery then still consists of a number of open gun emplacements, as was the case with many batteries at the beginning of the war. The fire control took place from a Verstärkt Feldmässige Leitstand. During the war, some fifty bunkers were built in the Zuidzand battery. The main armament consisted of four 9.4 cm guns. The bunkers hardly deviated from the standard design and on many German documents the were simply referred to as 671 S.K.
