The results of Montoito geophysics are very good and confirm entirely the presence of a ditched enclosure. Well, in fact they are at least three enclosures. The inside is a wavy one, surrounded by two concentric ones. For the moment, here is a glimpse of one gate in the southeast side of the outer ditch (smiling).
A gate that reminds the gates of the outside ditch of Perdigões and the inner gates of Xancra (see here).
The geophysics are from Helmut Becker, done in the context of the NIA-Era project on ditched enclosures plans and orientations directed by me (and with the participation of Tiago do Pereiro, that detected this enclosure in Google Earth).
