Heritage as sector, factor and vector: conceptualizing the shifting relationship between heritage management and spatial planning

Heritage is a highly malleable concept that is constantly in flux and whose substance and meaning are continuously being redefined by society. From such a dynamic perspective, it is inevitable that new approaches and practices have developed for dealing with heritage in the context of planned development. While most scholars acknowledge the existence of various heritage approaches, one of the major defining features is often neglected: their distinctive outlook on spatial dynamics. In this article, the shifting role and purpose of heritage conservation in Dutch spatial planning is analysed. A conceptual framework is introduced that frames three approaches to the planning treatment of heritage; the sector, factor and vector approach, respectively. Although these approaches have developed in a historical sequence, the new did not replace the old but rather gained ground amongst different actors. Thus, three quite different ways of treating the past in the present now coexist in Dutch planning practice. Although this coexistence can raise conflict, we argue that contemporary heritage planning does not call for a one-size-fits-all approach, but rather for a mixed-mode model
