_FAIRGROUND THEORY_ GOES BEHIND THE SCENES OF THE TRAVELLING FAIR – EXPLORING ITS DESIGN, ITS ATMOSPHERE, AND THE PEOPLE AND PROCESSES THAT MAKE IT HAPPEN – IN ORDER TO DEVELOP THE FIRST ARCHITECTURAL THEORY OF THE FAIR. Even well-known places can be made strange when the fair arrives in town. As visitors to the fair, we are willingly overtaken by the all-round intensity of the environment: loud, fast, bright, busy, and disorientating. Yet the design of the fairground site and its rides – seemingly so anarchic and chaotic – involves extensive considerations which are usually invisible to visitors. This book reveals these considerations, uncovering the relational architecture of events, bodies, networks, and machines which has long constituted the hidden life of the fairground. Combining extensive fieldwork and archival study of travelling fairs in the UK, the study also connects to other examples from around the world – temporary, ephemeral, and permanent architectures from World Expos and pleasure gardens to amusement parks and parades. Deploying event theory, process philosophy, and the work of thinkers including Whitehead, Simondon, and Stengers, _Fairground Theory_ situates fairs – both historic and contemporary – within a sustained theoretical exchange with architectural, urban, social and cultural theory.
