An initiative of the German Federal Cultural Foundation (Kulturstiftung des Bundes), German and Polish artists and art profesionals developed joint cultural projects between 2004 and 2006 with a view to long-lasting and intensive collaboration. The 22 projects addressed questions of current interest, and often took place away from large urban centres. The website BüroKopernican Turn organises projects, materials and texts into thematic blocks and is available in German, Polish, and English.
