This article explores the relevance of normativity for the critical term 'museality.' The normative structures that become visible in museum practice are outlined in connection with the practice of appropriation. The relations between museum practice and the ruling paradigm of incumbent political systems are shown as strategies of legitimization. An additional focus is laid on the blurred boundaries between museums and temples. Finally, the 'ethization' of museums in recent decades is discussed. It is shown that normativity is a central aspect of museality, being correlated to all its facets.
