The first traces of human occupation in the current municipality of Lousada date back to the 3rd-4th millennium b.C. and are a result of the first agricultural communities' activity of the Neolithic period. Amid these, we point out the necropolis of Serra de Campelos (Lustosa), a funerary monument ensemble of diverse typology (megalithic tombs and sepulchres, megalithic or not) attributable to the late Neolithic period. Despite the studies, still in embryonic stage, it is also possible to announce some notes relative to the Late Bronze occupation in this region. Indeed, the occupation strategy of these shepherd-farmer communities went mostly through the occupation of separate hilltops in the landscape, with the intention of dominating the main water courses and territory entry passages. An example of this period and this particular type of occupation seems to be Cabeço da Agrela (Lustosa) where, in the scope of the prospection works to the revision of the Archaeological Chart, some ceramic fragments and a tip of a silex arrow have been collected, and still the fortified village of S. Domingos, an archaeological site with an ample diachrony, whose occupational exponent is seen already during the Iron Age period. This Age is also represented in a considerable number of fortified villages, dispersed a little throughout the municipality's geographic area. From these, the imposing dimension and strategical location dominating the landscape give a special spotlight to the villages of Mortórios (S. João de Covas), Alto de Nevogilde (Nevogilde), Pias, Bufo (Sousela), and S. Domingos, perhaps one of the most monumental fortified villages of the Sousa Valley's region, where, since 1994, successive excavation campaigns have been carried through.
