Our designed environment is rich in buildings and green spaces that previous generations have built up with efforts and costs. These include prominent examples such as churches, castles and parks, which are generally appreciated; but they also include less prominent buildings and sites, which are given little attention. Sometimes they are even neglected or disfigured beyond recognition. Here, it is important to analyse which qualities lie dormant in the stock and how they can be vitalized. The research line revalorisation of cultural heritage stands for a sustainable and culturally conscious approach to existing architecture and landscape. This can be concrete investigations and measures for the revitalization of buildings and sites; but it can also be thematic studies that sharpen cultural awareness, serve basic research or contribute to future discourses with historical reflections.
