An outline is presented of the main results of a recent project on the dating of early Neolithic causewayed enclosures in southern Britain and Ireland. Nearly 40 enclosures have been dated. Over 400 new radiocarbon dates were obtained, and analysed with a roughly equivalent number of existing dates. Radiocarbon results were modelled in a Bayesian statistical framework, giving date estimates of much greater precision than had been the case before. As a result, we can now offer not only much more detailed histories for individual sites but also a much more comprehensive chronology for the causewayed enclosure phenomenon as a whole in southern Britain. An outline of their place within the early development of the southern British Neolithic is also briefly presented.
