They are a symbol of a totalitarian and paranoid system: 750,000 Bunker were built by the Albanian dictator Enver Hoxha from 1967 to 1986; that makes one bunker for each Albanian family of four. But the concrete mushrooms were not created to protect the population, but to defend the country in case of an invasion. Each Albanian received basic training to be able to shoot enemies out of the “concrete mushrooms” with a firearm. After the collapse of the communist dictatorship in 1990, many bunkers were first transformed into art objects; but in recent years they were actively destroyed – mostly for ideological reasons, but also to use materials like steel or concrete for other buildings. In his book “Concrete Mushrooms” the architect Elian Stefa dealt with this stone legacy of the dictatorship. In an interview he tells us about their function and importance.
