This paper focuses upon the practice of conservation applied through the planning systems of three European countries, Ireland, the Netherlands and England, here termed conservation-planning. The values and validated practice of conservation-planning are considered in terms of the concept of Authorised Heritage Discourses (AHDs) that are internationally-shaped but nationally articulated in each country, and by a distinct conservation-planning social entity that may be described as an ‘assemblage’. The post-2008 period has seen over-arching economic similarities in economic and political forces affecting conservation-planning practice in each country. In each case public-sector austerity measures have been accompanied by ideological re-positionings over the role of the state and a greater emphasis upon ‘selling the historic city’ has been accompanied by a declining public-sector capacity to manage change within the frame of traditionally established AHDs. The partial withdrawal of the state has in each case resulted in adjustments in the construction of the assemblage and thus in the ‘ownership’ of the AHDs with a greater involvement of the private sector in these processes. Despite similarities in conservation discourse, shaped by an international AHD, differences exist between the countries considered, which we can better understand by reference to the conservation-planning assemblage in each country.

This report summarises the findings of the JPI Heritage Plus PICH Project’s nvestigation of the impact of the reform of urban planning on the historic built environment. The project team conducted twelve in-depth case studies in Italy, the Netherlands, Norway and the UK covering three settings: the built heritage of historic urban cores, former industrial areas and the urban landscape. The findings are more fully reported in three comparative reports which compare findings for each setting in the four countries; in four national reports which look across the three settings in one country; and 12 case study reports.@en
