We know now that Perdigões ditched enclosures started by the middle of the 4th Millennium BC. That it has developed during the Late Neolithic to became already a large enclosure. The new assemblage of radiocarbon dates shows this. But also shows something else. That the earliest chalcolithic ditch at Perdigões is the small ditch 10 and that it defines an enclosure smaller than the Late Neolithic large one. Interesting don't you think?
The temporalities of Perdigões are getting better characterized by the recent work developed by NIA-ERA (that is directing the global program of research) and ICArEHB at Perdigões. But this work also shows that many surprises may be ahead. This is a complex and chellenging site. It is a privilege to work there.
