At the heart of this study are the early Neolithic chambered tombs of the Irish Sea zone, defined as west Wales, the west coast of northern Britain, coastal south and western Scotland, the western isles and the Isle of Man, and the eastern coast of Ireland. In order to understand these monuments, there must be a broader consideration of their landscape settings. The landscape setting of the chambered tombs is considered in detail, both overall and through a number of specific case studies, incorporating a much wider area than has been previously considered. Cummings investigates the background against which the Neolithic began in the Irish Sea zone and what led to the adoption of Neolithic practices, such as the construction of monuments. Following on from this, she considers what the chambered tombs and landscape can add to our understanding of the Mesolithic-Neolithic transition. This volume aims to incorporate landscape analysis into a broader understanding of the Neolithic sequence in this area and beyond. It will provide an introduction to the Mesolithic and Neolithic of the Irish Sea zone, as well as a summary of previous work on this subject. It also offers a starting point for future research and a better understanding of this area.
