0 Euro - Fort Eben-Emael

Fort Eben-Emael, built by Belgium between 1931 and 1935 to guard the Albert Canal and the Dutch border, fell to a German glider assault on 10 May 1940 — seventy-eight paratroopers neutralized a garrison of over 1,200 men in under twenty-four hours, a humiliation that prompted significant rethinking of fixed fortification doctrine across NATO planning circles for decades afterward.
