Very interesting exhibition called Usures at the Belgian pavilion at the 12th Biennale inVenice, Italy. The belgians of Rotor have investigated the phenomenon of material wear in buildings. They have presented random parts of exisiting building interiors and taken them out of their context. By doing so they show the beauty of used everyday materials and turning them into a piece of art, Arte Povera. But mostly the exhibition underlines that – contrary to general believe – material wear is not something that can or should be avoided at all costs but it is an inevitable process that reflects the very basics of architecture, human activities.
