Book excerpt: Of all Britain's great archaeological monuments the Iron Age hillforts have arguably had the most profound impact on the landscape, if only because there are so many; yet we know very little about them. Were they recognised as being something special by those who created them or is the 'hillfort' purely an archaeologists' 'construct'? How were they constructed, who lived in them and to what uses were they put? This book, which is richly illustrated with photography of sites throughout England and Wales, addresses these and many other questions. After discussing the difficult issue of definition and the great excavations on which our knowledge is based, Ian Brown investigates in turn hillforts' origins, their architecture, and the role they played in Iron Age society. He also discusses the latest theories about their location, social significance and chronology. The book provides a valuable synthesis of the rich vein of research carried out in Britain on hillforts over the last thirty years. Hillforts' great variability poses many problems, and this book should help guide both the specialist and non-specialist alike though the complex literature. Furthermore, it has an important conservation objective. Land use in the modern era has not been kind to these monuments, with a significant number either disfigured or lost. Public consciousness of their importance needs raising if their management is to be improved and their future assured.
