Digging a monument

Salgada, Borba (Évora, Portugal)

In this chalcolithic site we are digging, on a rescue excavation, part of a ditch, cut through the schist bed-rock.
The works, with a small team, go in alentejan way: slowly, very slowly.
I will keep showing some images of the excavation, as it goes deeper. For now, we have a curvilinear ditch, 1, 5-2 metres wide, with a narrow _(0,5 m) part, which is supposed to correspond to an entrance in the enclosure. On the top of the infill, the sediments are mostly composed by burned clay, with vegetable inprints, and beneath that layer, we are starting the dig others with plenty of pottery sherds. Stone axes have already been found.
