This article identifies cultural policy concepts to understand cultural heritage, both as a frame of reference for cultural histories and traditional narratives, and to create links to current processes of change. All too often, current concepts view cultural heritage as a strong foundation. This may indeed provide societies with a firm footing, but it seems to lack the flexibility that is required to tackle the challenges of today. The concept of a glocal self links the experience of cultural heritage with forms of cultural mediation and arts education that have a postcolonial orientation. It is a proposal for how cultural heritage sites could bring together these two aspects—a firm foundation and also flexibility. This article uses the example of the Berlin Palace (Stadtschloss), which has been reconstructed in the form of the Humboldt Forum. It faces a dual challenge: to remind us of the history of Prussia and its colonial past through its architecture, while at the same time acting as a place of reference and reflection on cultural diversity.
