The bunker, located at the Otok channel in Górki Noteckie, is an element of the German fortification lines of the Pomeranian Wall. It is a machine gun bunker characterised by short construction time and easy camouflaging. In some of the bunkers of this type, fortress furnishings were installed. Renovated in 2007, the bunker is the central element of the Fortification Open-Air Museum. Other fortification structures include 2 bunkers, road blocks and a water dam.
