A military bunker located in Switzerland, a country renowned for its extensive network of defensive fortifications. Switzerland has constructed over 374,000 bunkers since the 20th century, making it home to one of the world's largest bunker systems. These structures were built as part of the Swiss National Redoubt strategy to protect the country from potential invasions during World War II and the Cold War.
Many bunkers remain hidden beneath the surface, camouflaged to blend into the landscape, while others have been repurposed for civilian use or preserved as historical curiosities.
