PurposeThe integrity of heritage and landscape hinges on protection and restoration policies. Such policies are implemented through the determination of buffer zones that most of them are mainly based on the self-absorbed view, which isolates cultural sites from the community, instead of the more inclusive perception-based view. This study used perceptions as a base in identifying buffer zones in Anahita Temple, in comparison with previous study.Design/methodology/approachAccordingly, two parallel and qualitative methods were implemented. First, the site inventory approach was used to determine physical buffer zone, and then historical and temporal perceptions were used to determine a perception-based one. In addition, integrated buffer zone was defined based on two approaches. Finally, the participatory importance and performance analysis were proposed in order to conservation strategies formulation.FindingsThe results indicated that a physical buffer zone isolates the historical site from its landscape, thereby presenting challenges. By contrast, constructing a perception-based one not only maintains the integrity of the landscape but also creates correspondence between the landscape and people's mental map of the site.Practical implicationsMaintaining the site's integrity is expected to encourage participation from the local community and fuel more effective conservation efforts but it also introduces challenges given the need to impose new regulations.Originality/valueDespite various studies on role of perception in Historical Landscape, less attention has been paid to the role of perception in definition of heritage buffer zone. Therefore, the main goal is to develop a framework to determine the buffer zone of heritage sites by providing a sample.
