Bunkers are still omnipresent in Europe’s landscapes today. There are hundreds of thousands of them across Europe, most of them made of steel concrete. For tiny Albania alone, estimates run up to 200,000 standardized midget bunkers, apart from an enormous government bunker for the former potentates. The oldest of these concrete fortifications hail from the time before World War I, when the brick-walled fortresses of the 19th century needed massive strengthening due to new armor-piercing ammunition.
After the experiences of trench warfare in WW I, several European post-war governments opted for elaborate bunker systems along their borders as a supposedly impregnable line of defense. Once restricted areas, they are now either ruins or mementoes of, both, the hot and the Cold War. In two episodes, we trace the story and the architectural highlights of eight of these secret bunkers.
