Calcestruzzo: uso e non-uso nelle ricostruzioni di Josef Wiedemann a Monaco di Baviera

Josef Wiedemann is one of the most important architect for the Munich's reconstruction after the second World War. Munich was damaged, not so deeply as other german cities (Frankfurt, Köln), but starting from some months before the end of the war it planned how to work fast to go through the situation and make something good out this dark piece of its own history. The plan by Karl Meitinger (1950) shows clearly how "the heart of the city" was: a yellow hatch covers the buildings "completely or quite whole disappeared". In Wiedemann's poetic facing with ancient damaged buildings it's recognizable a choice that links all his "Wiederaufbau": the new surface is always covered by the same material of the old building, bricks follow bricks, stone follows stone. In the new buildings he projected, he is used to treat concrete as a material that can be shown, but it seems that he doesn't think he can do the same when he's working with ancient stuff. "Use and non-use" of concrete is a possible way to analyze Wiedemann's reconstructions, as we can discern between building which are integrated with old materials (the Glyptothek for example) and building with modern concrete structures. But "Use and non-use" is also an attitude of the architect, who uses concrete but he hydes it structure with a different skin, he doesn't let concrete to be expressed as a surface material near a older one. The thesis is carried on through two reconstructions between '50es and '60es years, the first is Alte Akademie's reconstruction and the second one is Siegestor reconstruction.
