This paper reviews the recent opening of the gallery “London, Sugar and Slavery” at the Museum in Docklands, in London, England. By looking at the exhibition from inside as well as from a wider context, this text links the main aims of the gallery and the Museum with current discussions of museology and material culture. Thereby this work assesses and underlines the importance of the historical object as a trace and representation of the social; the museum as a meeting place of contemporary debates and the material culture studies as a common place to bring together, objects, people and social and cultural phenomena. These three points have been found clearly within the gallery and therefore it becomes a watch-worthy example of one of the several roles of material culture in society.
