A military bunker located near Éperlecques in northern France, in the Pas-de-Calais department. This region was heavily fortified during World War II as part of the Atlantic Wall defensive system constructed by Nazi Germany. The area around Éperlecques contains several notable fortifications, including the massive Blockhaus d'Éperlecques, a protected V-2 rocket launch facility that now serves as a museum.
The local terrain and proximity to the English Channel made this area strategically important for German military operations during the war.
