# Disseminating the Past in 3D: O Corro dos Mouros and Its Ritual Landscape (Galicia, Spain)
## 2 Materials and Methods  
### The Choice of Site and Its Characteristics  
This set of digital technologies has been combined to obtain a product of scientific dissemination of interest to the general public and specialists, and this means that the final work is not just a technical report but a material designed to share knowledge with broad audiences. As an example, we have chosen a specific archaeological site, O Corro dos Mouros (OCM) and its immediate surroundings, a ritual landscape where research has recently begun, and which has proved to be a perfect experimental laboratory for the application of the digital technologies just mentioned. O Corro dos Mouros is an archaeological site located in Galicia (parish of Santa Maria Madalena de Adai), in the central-western part of the municipality of Lugo, on the Monte de Penas del Caldeiro-Adai and close to the Mino River (Figure 1). This site has been excavated in 2023 and 2024. The 2023 excavation was funded by the USC (University of Santiago de Compostela), and the 2024 excavation was funded by the Xunta de Galicia. The typology of this site is new to the region, called _tipo-Roda_ (Figure 2). _Roda_ means wheel in Galician language, this is the toponym more frequent for these places and indeed its shape is seen from the air as a wheel, an image that is quite easy to identify. It should be understood as a new monumental architecture emerging within a general funerary context, recently synthesised for the Middle and Late Bronze Age in Galicia [26], in which the architecture known up to now is characterised by isolated burials (cists and pits) invisible in the landscape, and the reuse of megaliths from the previous Neolithic period. Research into this type of site is still in its infancy but it promises very interesting results that will contribute to significantly expanding and changing our knowledge of the region between the end of the second millennium and the end of the first millennium BC, that is, from the Late Bronze Age to the end of Second Iron Age. Preliminarily, a _Roda_ is a circular-shaped archaeological site delimited by monumental stone-made architecture and a ditch, hosting inside burials and other structures so far possibly associated with funeral rituals. These places could be considered a necropolis for the death (inside the circle) and meeting places for the living (outside). Its chronology varies between the 15 th and 3 rd centuries BC. _Rodas_ are archaeological sites mainly, not exclusively, linked to funerary or/and ritual functions. There are currently eight _Roda_-type sites excavated in Galicia [27]. In particular, the architecture of O Corro dos Mouros is among the best-preserved sites. From a chronological perspective, six dates have been obtained. Two place the site's construction and use between 13 th and 11 th centuries BC cal. Four align with the 8 th-6 th centuries BC cal, indicating a continuity of use over several centuries. From the material point of view, the O Corro dos Mouros excavation has yielded 3300 artefacts, currently in the study phase. This represents a density of 66 finds/m\({}^{2}\), a remarkable figure when compared to Ventosinos site (another nearby site located a few kilometres away from OCM to the east of the Mino River), where 1946 artefacts were recovered from 7000 m\({}^{2}\), resulting in a density much lower than OCM of only 0.27 finds/m\({}^{2}\). In terms of artefacts, there is evidence of intensive occupation, with around two hundred vessels (based on 2296 ceramic fragments) and 546 lithtic artefacts, most of which are associated with grinding and crushing food, wall bonds or ritual objects such as slate and soapstone discs. These pieces were selected from a very wide range of materials from these periods. In the early phase, there are vessels and flat slabs placed on the ground near the parapet inside the enclosure. In the first millennium, the ritual of depositing some containers accompanied by discs associated with later dates continued, as well as a large pit sealed by a small menhir.
