Utilitarian greyware ceramics are one of the most abundant artefacts at rural sites in Medieval Catalonia, Spain and were manufactured by numerous long-lived production centres. The stylistic homogeneity of this class of pottery has traditionally restricted its contribution to the archaeological interpretation of the region. However, recent scientific analyses of excavated kiln sites are offering new perspectives via the establishment of compositional reference groups for greyware ceramics. Using one such dataset, from the large workshop of Cabrera d'Anoia, this paper examines the distribution and consumption of utilitarian grey pottery at 25 Medieval sites across Catalonia. The study reveals a pattern of several regional production centres distributing their goods to small villages within the surrounding countryside and in some cases competing for rural markets. This is interpreted in terms of the mechanisms by which greyware pottery was distributed, as well as the socio-political and religious influences on its supply and demand in Medieval Catalonia.
