Ditched enclosures in central/north Portugal (Yellow circles). Santa Bárbara is number 30.
The actual distribution of ditched enclosures in Portugal shows a clear concentration in Alentejo region, in the Guadiana and Sado basins. But some enclosures with ditches also started to appear in the north part of the country. First in the littoral. But in the last years they were detected also in the hinterland, in Beira Interior.
Is the case of the ditched enclosure of Santa Bárbara, Sabugal (Peresterlo & Osório, 2005). Unfortunately there is not much information published about the site and its negative structures. Through some newspapers articles we know that there are pits and a ditch (25 meters long and 3 meters wide), apparently dating from the Chalcolithic.
The site is very near the Spanish border and that region of Portugal is part of the western traditional pathway between the two Iberian central Mesetas and a natural extension of the central territories, both north and south of the Central Mountain System. Well, in both areas, the Madrid region and the Douro valley, the last decades have revealed a significant density of ditched enclosures. Besides, the Beira Interior region is also well connected to the South, being part of that north-south route that links three mains river valleys: the Douro, the Tagus and the Guadiana.
It is a linking region, well marked in several historical periods (such as in the Bronze Age through stelae distribution), connected to areas where ditched enclosures are very well represented. So, it was just a matter of time before they started to appear here too. And more are expected for the near future.
