This is a Regelbau 395 type military bunker, a standardized German design from the Second World War. The designation 'Unterstand mit Beobachter' translates to 'shelter with observer,' indicating its primary function as a protected observation post for directing artillery fire or monitoring enemy movements. Such bunkers were a common component of German coastal and frontier fortifications, including the Atlantic Wall.
Constructed using the Regelbau (standardized construction) system, these bunkers featured reinforced concrete walls and roofs to withstand conventional artillery. Their design prioritized a protected vantage point for a small observation crew, often equipped with periscopes or direct vision slits. The specific historical unit or event associated with this particular bunker at the given coordinates is not detailed in the available information.
Located in Germany, this structure is part of the extensive network of WWII-era fortifications that dotted the European landscape. Its current state—whether intact, ruined, or repurposed—is not specified. Like many such relics, it represents a piece of military heritage from the 20th century, subject to the interests of urbex (urban exploration) and historical preservation.
