Northwestern Iberian Tin Mining from Bronze Age to Modern Times: an overview

International audienceThe northwestern Iberian Peninsula has been well known for its mineral wealth since classical times, including for gold and for tin. In fact, the Iberian tin belt is the largest in western Europe (covering an area of c.200,000 km2), containing tin deposits that were accessible from ancient times. Nevertheless, few archaeological studies have been dedicated to ancient tin mining in the region, unlike gold mining, for which major mining complexes are known from Roman times (e.g. Las Médulas, N Spain, and Três Minas, N Portugal). In this paper, evidence for tin mining in different periods, from the Bronze Age to modern times, is discussed, based on selected casestudies, using various approaches developed for the study of ancient and modern tin mining, by members of the present Iberian Tin Research Group. An introduction to the geographical and geological contexts of Iberian tin, and the history of investigation on Iberian tin mining, is included
