Ever since large amounts of Bell Beaker complex pottery were first discovered within megalithic graves in north-western France, the Bell Beaker has been tightly tied to the ‘megalithic phenomenon’. However, the fact of construction of these various kinds of megalithic monument during the Middle to Late Neolithic pre-dates the users of Bell Beakers. While this is a case of the re-use of older funerary monuments, it is assumed that Bell Beaker funerary practices witness a shift from Neolithic collective burial to individual inhumation. For a long time finds from the megalithic graves have constituted our main source of information on the Bell Beaker complex in north-western France. However, these ‘artificial caves’ have biased our understanding of the Bell Beaker complex and, in particular, of its funerary practices. The re-assessment of old finds and recent large-scale excavations have brought to light a large number of new sites, revealing a greater diversity in Bell Beaker funerary practices in the region than had been perceived previously. In the first part, we set the broader picture, stating what we know or can say about funerary practices during the Recent and Late Neolithic (3350–2550 bc), before the beginning of the Bell Beaker phenomenon. We then discuss the different Bell Beaker burial practices (2550–1950 bc), their chronological and regional variabilities, and, above all, the research biases that might have affected their understanding.
