The archaeological site of São Julião is a Late Bronze Age settlement, located on the coastal platform between Douro and Vouga rivers, which has been the subject of systematic research projects since 2014. Its most striking structures are the stone wall that delimited the enclosure and a megalithic mound, violated or reused in modern or contemporary times. The archaeological collection includes a significant set of ceramics, objects in stone and metals, with emphasis on a pair of gold earrings, perhaps related to the evidence of metallurgy that is observed in the place. Currently, a site’s archeological conservation and enhancement program is underway, with the support of the Municipality.

The Castro of Salreu, located in the municipality of Estarreja (Aveiro, center‑north of Portugal), is one of the most coastal proto‑historic settlements of the region between Douro and Vouga rivers, enjoying a privileged location on a meander of the river Antuã. The site has been the target, in recent years, of archaeological works that uncovered structures in two main areas, one of a housing nature and the other, corresponding to the defensive and delimiting structure of space. The five archaeological campaigns carried out allowed the collection of more than 35,000 ceramic fragments, some lithic artifacts, an engraved plaque, few metal objects and a set of more than two dozen glass paste beads. It is proposed that their occupation occurred between the 4th/3rd centuries BC and the change of the Age.
