The Blockhaus canon WW2 is a Second World War German bunker located in northern France, near the Pas-de-Calais département. This fortified structure was part of the extensive Atlantic Wall defenses constructed by Nazi Germany during the occupation of France. The region around Saint-Omer and Watten became a strategic area for German military installations, including V-2 rocket facilities and heavy artillery positions.
The bunker's location in northern France reflects the importance of this coastline in German defensive planning against potential Allied invasion.
