KüVer Gruppenunterstand mit L2

A military bunker structure located near Bergen op Zoom, Netherlands, identified by the German designation 'KüVer Gruppenunterstand mit L2'. The name suggests a possible link to German coastal defense (Küstenverteidigung) infrastructure from the World War II era, as the Netherlands was occupied by Nazi Germany during that period. However, the specific historical details, function, and construction of this particular site are not confirmed by the available search results, which provide only general military reference information.
