The longhouse has been a turning point for research on prehistoric farming societies in Scandinavia for several decades. Yet, no comprehensive study has been made of this house type and its context, variations and social implications in the Far North. In this chapter, we present the currently available longhouse material within the three northernmost counties of Norway. The 50 longhouses that have been excavated within the administrative district of Tromsø University Museum are discussed in more detail. Our survey shows both similarities to and some intriguing variations from the longhouses in other areas of Norway and the rest of Scandinavia, concerning the chronology of various house types, building details and farm layout. All these aspects are obviously related to the particularities of the environmental, cultural and sociopolitical context in the north. However, the results are preliminary, as more thorough studies are needed, as well as more excavations employing current methodologies such as mechanical topsoil stripping, to ensure representative data.boreal times to the present, comprising Stone Age tent rings, semi-subterranean circular dwellings, large and deeply dug square and rectangular house grounds, as well as circular turf house grounds from the Early Metal Age onwards. From the Iron Age at least, the latter are associated with Sámi habitation (Olsen 1997). Various sized hearths associated with the Sámi, often dating as far back as to the Iron and Middle Ages, are also commonly encountered as surface structures. The shape, internal positioning (partly singular, partly in rows) and their placement in the wider landscape reflect different cultural and economic adaptations, such as the emergence of reindeer pastoralism in the Middle Ages (e.g. Sommerseth 2009;Hedman et al. 2015).The surface visible structures include a variation of house types from the Iron and Middle Ages in the mainly Norse/Norwegian areas (Olsen 1997). Among these is the house that is considered most typical for Germanic/Norse farming settlements, the longhouse (Figs. 1 and 2). The longhouses are relatively substantial structures, though not unique in their size. Some visible Stone Age houses, such as the so-called "Gressbakken" houses and some rectangular house grounds at the island Traena (Gjessing 1943, 62-65;Schanche 1994), are comparable in size and rectangular shape but follow other structural principles. They are therefore not easily
