The new ditched enclosure, with a gate in first plan.
A new ditched enclosure is being worked by Era in Alentejo. The water supply network of Alqueva is crossing another enclosure and a segment of a ditch will be excavated soon. It is a small ditch, defining an apparently circular enclosure located in a small elevation over a stream. It is located in the western limits of the distribution of enclosures in Alentejo, where some other ditched enclosures have been recently discovered by enterprises and by aerial photos, enlarging the number of ditched enclosure known in the Sado river basin.
