The vernacular architectural style is on the verge of disappearing in Transylvania because of the depopulation of the Saxon villages of German origin as a result of massive migration to Germany. The nomination of Hărman cultural property on the UNESCO list is part of an international legal framework, and the Convention on the Vernacular Architectural Heritage protects this architectonic style because it represents the expression of a community’s culture, as well as its relations with the territory and cultural diversity. The proposed area includes a 63.47 ha perimeter of the historic centre of Hărman, consisting of a compact group of 260 houses and the entire fortified Evangelical Church. A buffer zone of 290.09 ha is included alongside this area. Thus, we propose that Hărman be nominated for the Cultural Evolutive Landscape Category under cultural criteria ii, iii, and v. The assessment of the authenticity and conservation status of Hărman cultural property was carried out by applying the following criteria: form and design, materials and substances, use and functions, and location and positioning, which apply to the tangible features of the landscape. Furthermore, the evaluation of intangible heritage was achieved by applying the following criteria: traditions, techniques and management system, language and other forms of intangible heritage, spirit, and feelings.
