About the Presence of Exotic Materials in Some Funerary Megalithic Monuments in Alentejo (Portugal): The Cases of Cinnabar and Amber

In the Iberian Peninsula, the Alentejo region is particularly important for its number of Megalithic monuments, both funerary and non-funerary. The majority of these monuments have been excavated during the last century, and nowadays, despite the fact that the methodologies used were not always the most appropriate, large numbers of archaeological artefacts are stored in various National Museums.
