At Julianadorp aan Zee a very interesting battery was built.
It got the name Seezielbatterie Zanddijk and consisted of two casemates especially built for the double 15cm turrets of the battleship Gneisenau.
The battery was led by a M 120 (gone) and the additional ammo was to be stored in two planned 134s. This is Bp 47.
It lies near the Landfront, so infantery defences were nearby. These can be found south of the battery and consist of 2 x 653, a Ksb and Höckers.
The Pak bunkers are covered, we think to have found one.
