Cardoso, João LuisNeto, NunoRebelo, Paulo2025-06-112025-06-112025-05http://hdl.handle.net/10400.2/19926The Neo-Chalcolithic site of Travessa das Dores is the first to be recognised in the urban area of Lisbon with prehistoric storage and defence structures, closely interconnected, constituting without doubt the most important vestige of the settlement of that period studied to date. To increase the scientific importance of this site, a large adjacent area, called Rio Seco, was identified and excavated a few years later, in which, among others, several large dry stone walls were identified, some rectilinear, others arched, indicating the existence of boundary walls or supporting walls for agricultural plots, whose presence is justified by the basaltic soils present locally, of high agricultural suitability. Therefore, while Travessa das Dores was the storage site, Rio Seco was the site of the respective agricultural productions, thus constituting evidence, until now unknown in portuguese and even international archaeology, of the direct relationship between these two realities, relating to a single prehistoric community, based there in the transition from the fourth to the third millennium BC.porNeolítico FinalEconomiaTravessa das DoresRio SecoLisboaLate NeolithicEconomyLisbonjournal article
