The overlapping of two different images allowed the identification of several sections of ditches in the large archaeological complex of Porto Torrão (Ferreira do Alentejo, Beja). Some are the continuation of ditches already surveyed (dotted lines), but others correspond to new ditches that define central enclosures, where at least one gate is visible.
This image was published in the book dedicated to the tholoi tomb of Cardim 6, available for download here.
