Zugang HGS is a military bunker located in northern France, near the Belgian border. The site appears to be part of France's Cold War-era defensive infrastructure, likely connected to the country's nuclear deterrence strategy. During the Cold War, France developed extensive bunker networks to protect command and control facilities, as well as to provide hardened positions for military personnel.
The region where this bunker is located has a long history of military fortifications, dating back to both World Wars and continuing through the Cold War period.
