Recent research has established that south Scandinavia during the Nordic Bronze Age was entirely dependent on imported metal. It was obviously in contact with other parts of Europe and must have participated in a system of long-distance exchange. It is not clear how it would have operated, but it helps to explain the importance of watercraft and drawings of distinctive artefacts in the rock art on the Baltic and Atlantic coasts. A different group of images can be associated with inland areas where the art has a more restricted lexicon. Can the borderland between these traditions shed any light on the relationship between the seashore and the interior, and might this help to identify places where artefacts changed hands? This paper presents the results of fieldwork between Lakes Vänern and Vättern in Västra Götaland county, southern Sweden. It considers the character of inland rock art and whether some locations with more complex panels were used as ‘aggregation sites’.
