Just discovered, while preparing a field prospection. The Impact Study refers prehistoric material at the surface. Google reveals the rest (or almost).
It is a big one (480 x 430 meters), more or less the size of Perdigões, and have two external ditches, one apparently linear and the other sinuous like Xancra, Santa Vitória or Outeiro Alto (but much bigger). Inside, we can almost see more two other smaller ditches.
Like Porto Torrão and Pijotilla, a stream cut the enclosure, with a North-South orientation.
It is, naturally, in Alentejo hinterland, in the Beja district. A work of ERA in a project of water supply of EDIA S.A.
