This book features text in English and German. Linking art and architecture is one of the great Utopias of our century. Art has been released from its traditional bonds and sees itself faced with a world that has made systems independent to the extent that a link between art and building based on the idea of unity is no longer admissible. The collapse of our 'world into pieces' also typifies that situation of the arts looking for new orders. Now, artist-architect Johannes Peter Holzinger, in co-operation with artists Eberhard Fiebig, Ottmar Horl/Formalhaut, Leonardo Mosso, Norbert Muller-Everling, Ansgar Nierhoff and Andreas Sobeck, working on the government buildings on the Hardthohe in Bonn, has succeeded in creating 'an avant-garde landmark that shows in the interplay of the arts that the avant-garde can also work positively in a team', as Dieter Ronte, director of the Stadtisches Kunstmuseum Bonn, put it in a contribution to this book. Holzinger links heterogeneous artistic positions in attempting an order of the different. The art in the outer areas of the complex mediates between the surroundings and the buildings. The visual signing system leads further into the centres, which are the same shape, of the existing administrative buildings, and creates some thing that is unmistakable there. The special structures designed by Holzinger, an intermediate form of architecture and landscape developed from the relief, include the earth itself, and in the casino architecture and art combine to form an indissoluble unit.
