Domestic architecture played a central role in the identity of later prehistoric communities, particularly in creating lasting bonds between the living and the dead. Acting as a conduit of memory and legacy for successive generations of inhabitants, roundhouses straddled the divide between house and memorial. The exceptionally well preserved Late Iron Age settlement at Broxmouth in southeast Scotland demonstrates the potential of biographical approaches in understanding the central role that roundhouses played in fashioning the identity of successive households, and the role of objects in constructing genealogical narratives.
