The Dolmen de Soto is considered one of the premier Neolithic passage graves in the Iberian Peninsula. Set within a flat fertile plain and c. 8.5km south-east of the town of Trigueros in Andalucía, this monument was in use some 5000 years ago and was part of a unique pan-Atlantic European cultural revolution that included ornamentation of the internal spaces of many passage grave monuments. The site was discovered in 1923 by Armando de Soto Morillas and subsequently excavated over three consecutive seasons by the German archaeologist Hugo Obermaier. The passage and chamber are constructed within a low circular mound that measures 75m in diameter, making it one of the largest passage graves in Europe. 



The Dolmen de Soto has recently undergone a significant restoration programme and as part of this project, engraved and painted images upon the upright stones within the passage and chamber areas were investigated and recorded by a team of international scientists between 2016 and 2017 using a variety of photogrammetric methods. This publication tells the fascinating story of the archaeological and historical context of the site, along with the methods employed and stunning results the project yielded.
