These papers come from a conference on Neolithic Causewayed Enclosures in Europe held in London in 1999. They present a series of snapshots of some of the sites and regions at the forefront of current research on causewayed enclosures in Europe, and as such are a complement to the Royal Commission on the Historical Monuments of England (RCHME) project which has systematically recorded all known Neolithic enclosures in England by both analytical topographic survey techniques and aerial transcription. The detailed regional data collected by the RCHME project has allowed a radical reinterpretation of these sites and the recognition that there are regional groups of enclosures. This series of papers serves to broaden the discussion about the structure and form of causewayed monuments beyond lowland England, looking at a wide geographical range of sites across central Europe, as well as considering some sites which do not conform to the traditional type but which have been proved by excavation to have a Neolithic context. This collection of papers provides a long-awaited and important addition to the debate on these enigmatic prehistoric sites.
