Freie kuste Callantsoog - Petten Jägerleitstelle Schneeglöckchen (Bpt. 53c)
Just outside the village of Schagen at the northside along the N248 in the direction of Callandsoog at Km-sign 4.4 is located the "Jägerleitstelle Schneeglöckchen".
It's a brick building in T-shape and was during the war surrounded with several antenna's to do the measurements for the fighter planes who were attacking the Allied bombers.
We assume that this locations is Bpt 53c, because on Baufortschrittkarte is mentioned a location for a Y-anlage Schagen with two ST-bunker planned but never build.
