A military structure identified by the designation 'Wa Ko Fest 2cm Flak' located near Calais in the Pas-de-Calais department of northern France. The name suggests a possible connection to German WWII-era military organization (Waffen-Kommando-Festung) and a 2cm anti-aircraft (Flak) weapon position. The site lies within a region that was heavily fortified by German occupying forces during World War II as part of the Atlantic Wall coastal defenses.
However, specific historical details, construction date, and exact function of this particular structure are not confirmed by the available search results, which focus exclusively on contemporary French nuclear policy. Current physical condition and accessibility are unknown.
