Iron Age Saunas of Northern Portugal: State of the Art and Research Perspectives.

Special buildings used as saunas have been found in certain large hillforts in the north of Portugal and in the Cantabrian coastal area of Asturias and Galicia in Spain. The principal aim of this study is to highlight the importance of these buildings in the archaeology and art of the European Iron Age, where they are very rarely mentioned. Two approaches are developed: in Parts 1 and 2, we explain the structure of the buildings, their function, and the current debate surrounding their dating. In Parts 3 and 4, further analyses are developed on their position in the landscape, associating the saunas with the public life of the hillforts, and on the decorative structure of the pedras formosas ('beautiful stones') found in some of them, and their relation to certain artistic trends in so-called Celtic art.
