Vernacular and World Heritage Impact Assessment: the case study of Patmos

Purpose: This article aims to raising awareness on the potential of the application of the Heritage Impact Assessment (HIA) methodology – developed by ICOMOS in 2011 – with a focus on UNESCO World Heritage sites that are characterized by a widespread presence of vernacular architecture, one of the most vulnerable and fragile typologies of heritage. Design/methodology/approach: Starting from a theoretical introduction about the recognition of vernacular heritage into the international non-governmental panorama, and the dynamics that are mostly affecting it, the present contribution focuses on the case study of the Chora of Patmos (Greece), a UNESCO World Heritage site since 1999. The research has been carried out as follows: (1) comparative analysis of selected literature for the theoretical part; (2) field research; (3) interdisciplinary research for understanding the features of the site and assessing potential risks; (4) project design and assessments of the potential impacts. Findings: The pivotal application of the HIA method on the case study of Patmos highlighted the importance of the methodology as an essential tool for facilitating management and safeguarding WH sites from possible threats due to development projects on vernacular architecture. Originality/value: The originality of the research presented here lies in the connection between three different topics: vernacular architecture, Heritage Impact Assessment and Sustainable World Heritage Management. In fact, its goal is to bring cultural heritage management and sustainable development closer together, by emphasizing that HIA should not be used as a tool to hinder development, but as a practice for shaping and evaluating projects that might alter or compromise the integrity and authenticity of WH sites in a sustainable and balanced way.
