Abstract

The prehistoric site of Monte das Pedras (Mina, Amadora): identification and characterization of a new possible Neolithic flint workshop This paper deals with the identification and characterization of a new possible neolithic flint workshop located in Lisbon peninsula, included in an area rich in human occupations of the 4th and 3rd millennia BC. By the analysis of the recovered data, as well as by the comparison with other similar sites, we advance the hypothesis that we are standing before an area dedicated to a specific activity — the exploitation of raw materials (namely flint) to the production of flaked stone tools — dependent of one (or more) of the various settlements of the ancient peasant communities that are known in the immediate area. By the same way, we seize the opportunity to re-evaluate the evidences of settlement of the surrounding area of the prehistoric site of Monte das Pedras, characterized by a curious heterogeneity of manifestations, mainly in the funerary universe. Therefore, we hope once more to contribute to a better understanding of the ancient peasant communities from the 5th to the 3rd millennium BC in Lisbon peninsula.
