Widerstandsneste 92 & Walzkörpersperre
The Flak gun emplacements were equipped with four 10,5 centimetre Flak guns. Besides the Flak gun it had a 5 cm KWK ‘KampfWagenKanone – tank gun’, Tobruks for mortars, Tobruks for Machine Guns, personnel bunkers, ammunitions storage and covered trenches. The unique feature of this Widerstandsneste is the Walzkörpersperre. This checkpoint in de antitank wall is so unique that it seems there are only 2 left in the entire Atlantic Wall.
The Walzkörpersperre is a ‘door’ in the Anti Tank wall. Two huge concrete blocks can be lowered by winches to seal off the entrance towards the Festung IJmuiden. Two tobruks are placed at either side of the Walzkörpersperre to protect the opening. A bit further down the tank wall is a tank ditch, protected by an integrated Pillbox, Regelbau 676. The Pillbox housed a PAK, a Panzer abwehr Kanone or Anti Tank Gun.
The complex lies in the dunes, a protected natural area and is not free to visit.
