The Linz Cafe is the fourth in the seminal series of books on architecture. The Linz Cafe describes the application of the theory to a single building commissioned by the organizers of the 1980 summer exposition "Forum Design" in Linz, Austria. From the Introduction: "The Linz Cafe is one of the first buildings in which I have succeeded in carrying out almost all the intentions expressed in the earlier volumes of this series. It is a small three storey building, built on the banks of the Danube in Linz." –Christopher Alexander. This book tells an intimate story of the conception and realization of the building.
