Monte da Contenda is much bigger and complex than we expected. The image suggests several enclosures with ditches and palisades, sometimes overlapping and with several going out of the surveyed area, announcing a quite large enclosure (about 300 or 400 meters diameter). There are linear wavy designs and the number of enclosing structures is bigger than in Perdigões. It is another amazing site and more food for thought about Portuguese Ditched Enclosures. And it shows that we are doing a good job with the identification of enclosures through Google Earth.
Part (about ¼) of the magnetogram of Monte da Contenda done by Helmut Becker in the context of the NIA project on ditched enclosures directed by me (it is raw data, steel needing a lot of work from Helmut to produce a clearer image of the enclosures).
