This article engages with certain peculiar finds and features that we have documented at former German WWII military camps in Finnish Lapland, with a particular emphasis on an excavated assemblage that has affinities to traditional ritual (sacrificial) practices. The relevant finds and features date from the post-war period, but they are meaningfully associated with WWII sites. We consider the possible connections of these finds and features to folk magic and the supernatural, especially with regard to boundaries and boundary-making. The material is interpreted in relation to the painful histories and memories of WWII in the high North, and in the broader context of northern ways of life and being and perceptions of temporally layered landscapes. More specifically, we focus on how locals have coped with the difficult and haunting presences of WWII in northern landscapes and mindscapes after the war in a particular natural, cultural and cosmological lived environment which people have long co-inhabited with various non-human and spiritual entities. We aim to contribute to the broader discussion of the folklore of WWII as a dimension in conflict heritage and memory.
