Fennoscandia archaeologica XXXIII (2016) Gørill Nilsen THE USE OF MARINE MAMMAL BLUBBER: PARAMETERS FOR DEFINING FAT-RENDERING STRUCTURES Abstract A large number of structures, primarily pits, dating to the Bronze Age / Early Metal Period and Iron Age are situated along the coasts of Sweden, Finland, Åland Islands and Norway. The article discusses a series of examples of such structures thought to be genuine fat-rendering structures located in the Counties of Troms and Finnmark (northern Norway), the Åland Islands (Finland), and Västerbotten (Sweden), and compares them to contemporary pits from Sweden and Finland, the interpretation of which is less certain. Results from archaeological excavations and experimental reconstructions of north Norwegian slab-lined pits form the basis for discussing the interpreta- tions given to the structures in question.
