In this set of outcrops, 125 motifs were counted. It was possible to perceive that segmented circles dating back from prehistoric times occur in 29 archaeological sites of the region, either engraved on outcrops detached from the ground or leveled with it. The combination of all these tools allowed to build an inventory, and to discuss the collected data, shedding light about possible answers to the defined objectives.

For this purpose, it was used the vast existing bibliography available related on the subject, so as fieldwork (through archaeological prospecting and photography) and office work (including the use of new technologies, such as photogrammetry). To carry out this work, a list of objectives was prepared. To this end, it was decided to study the engraved prehistoric segmented circles in theĬircumscribed space of the Northwest of Portugal. The main objective of this work is to increase the knowledge about specific topic related to Portuguese rock art.
