The grass-covered top of the Brough of Deerness, a small sea stack in Orkney, Scotland, holds the remains of a substantial Viking Age settlement and associated chapel. The chapel was excavated by Christopher Morris in the 1970s and discovered to have two phases, one above and one below an Anglo-Saxon coin minted between 959 and 975. New excavations of two buildings from the surrounding settlement aim to illuminate the function of the site, and to inform our understanding of the relationship between power and religion during the Viking Age diaspora. At least one of the buildings was a domestic dwelling, of typical Scandinavian style, abandoned in the 11^th to 12^th centuries. However, both structures represent only the top of a long stratigraphic sequence, with underlying middens radiocarbon dated to as early as the 6th to 7^th centuries A.D. In its latest phases, the site was probably a chiefly stronghold (as previously suggested by Morris) with a symbiotic relationship with surrounding farms. In this preliminary report on new research, several models are tentatively proposed to account for the role of such a settlement within the political economy of late Viking Age Scotland.
