Cultural heritage, preserved and managed in an appropriate way, can play a decisive role in spatial development. This is the focus of the VILLAS project. The project's main aims consist in improving and revitalising the aesthetic and economic aspects of architectural heritage by creating an evaluation model and defining a compatible, reusable strategy tool according to the planning criteria and spatial policies of the CADSES area. In the long term, the project is expected to have a positive effect on regional communities and economies through the increase of knowledge, cultural tourism, investment possibilities, etc. and in a broader sense the amelioration of juridical instruments at national and European level. The possibilities of intercultural dialogue and the multidisciplinary approach of the topic will, on the one hand, achieve the relevant sustainable development requirements, and, on the other hand, contribute to the support and stability of the area.
