Within a landscape, boundaries are the physically or socially defined lines that mark the limits of spaces. They can appear static and binary, and therefore analytically restricted. Yet it is argued here that while space is often analyzed in archaeology to inform social, economic, or institutional interpretations of a landscape, the analysis of boundaries is a complimentary method that captures movement, control, and prohibition mechanisms. Analyzing boundaries is shown to reveal aspects of change – sometimes diachronic and sometimes ephemeral – and a malleability that is often linked to materiality. The examination of the early nineteenth-century historical boundaries of Point Puer, a juvenile convict prison (1834–49) located in lutruwita/Tasmania, Australia, is used as a case study to illustrate their common archaeological forms. It is reasoned that the analysis of boundaries contributes dynamic interpretations of historical landscapes by theorizing boundaries as spatial frameworks to examine social and experiential elements of space.
