What is a museum in Kenya? How was this concept introduced, understood and taken over? The museum, one of the places that expresses and displays the heritage discourse, can be analysed as an apparatus. This approach gives the means to tackle the dynamic balance between the rules and knowledge that establish the apparatus and the social and political functions that can be incorporated. This double process of social learning and territorial interpretation is the appropriation of a heritage apparatus. This paper will tackle an attempt to build a museum from a marginal community in Kibera slum. The goal is to grasp the meanings of the contemporary appeal of heritage in margins and the logics of the construction of a place of culture.
