A Swiss infantry bunker, designated Infanteriewerk Fels A5868, located near the town of Reute in the canton of Appenzell Ausserrhoden. The structure is part of Switzerland's extensive network of military fortifications constructed primarily during the World War II and Cold War periods as part of the country's defensive strategy of armed neutrality. These bunkers, often integrated into natural terrain like rock outcrops ('Fels' meaning rock), were designed to control key topographic features and transportation routes.
The specific historical details, armament, and operational history of this particular position are not confirmed in available sources. The region of northeastern Switzerland has a long tradition of fortification due to its proximity to historical invasion routes. The current physical state and accessibility of the structure are not documented in the provided information.
