The European town and city represents compact urban structures, building fabric from different eras, and dynamic use for social activity, housing, and work. The preservation, renewal and development of the European town and city – with and based on its current architectural and spatial forms – has for several decades been a project faced together by the national government, the federal states, and municipalities. For more than 45 years, one central instrument for coping with the complex challenges of urban development in Germany has been the Urban Development Support scheme provided by national government and by the federal states. The Protection of Urban Architectural Heritage scheme works towards integrated urban development based on the existing building stock. In its current form and following its extension across Germany, it has across Europe become a byword for successful conservation of cultural heritage and sustainable development of the (European) town and city. On the occasion of the European Year of Cultural Heritage 2018, this is a report on the programme, its projects, and the experiences thus gained.
