P Line Bunker in the Pyrenees

A fortified bunker located in the Pyrenees mountains, part of the Línea P defensive system built by Spain between 1944 and 1948. This military structure was constructed during the final years of World War II as part of Spain's defensive strategy to protect its northern border. The Línea P, officially known as the Pyrenees Defense Organisation, consisted of semi-buried reinforced concrete bunkers connected by tunnels, positioned at strategic high-altitude locations throughout the mountain range.
