Shining a light on some of the most interesting research results on megalithic cultures, as well as their contemporaries, these 16 papers from the European Megalithic Studies Group symposium (Santiago de Compostela, Spain), cover monuments from Germany, moving down the Atlantic Facade across to Ireland and then back to the Western Mediterranean. Issues presented in this volume include temporality and mobility (both at the broad scale and at the local scale), social organisation & settings and external relationships. The methods used to investigate these themes are various: bio-molecular and isotopic analyses, typo-chronology, targeted excavations & radiocarbon dating, material cultural analyses, 3D models, ceremonial & funerary/burial practices (including osteometrics) and large-scale prospection. New methods researching the materiality and symbolism of monuments are also presented; some incorporate the role of the natural world. Alongside them are other contributions focusing on the key characteristic of megalithic monuments – the skilful and purposeful arrangement of large blocks of stone – and their interpretation. Discoveries include the intriguing return of large & complex ceremonial timber circles in active megalithic areas, presenting a significant contrast to what was considered the main funerary expressions in South Portugal. Ultimately, through the application of new, or differently applied, technologies and ways of thinking, this volume offers a series of studies that remove some of the mystery that surrounds these mementos of another time.
