The number of ditched keeps increasing in Portugal (namely in the South). Having a good chronology of these sites is crucial for the understanding of their emergence, development and fall. I have registered know almost sixty in Portugal, but just 1/6 has been dated by radiocarbon.
Chronology of ditched enclosures of Recent Prehistory in Portuguese territory.
Next week, in the first Congress of the Portuguese Association of Archaeologists I will be presenting a paper that does the synthesis of the available radiocarbon dating information for these enclosures and, based on that, it will be underlined the main tendencies that can be perceived in these architectures during the Neolithic and Chalcolithic.
Since the proceedings will be released during the congress, the paper will be available by the end of next week.
