Since his first interactions with Welsh miners striking in London in 1929, Paul Robeson has been considered by some as an “honorary Welshman.” While the African American actor, athlete, activist, singer, and scholar never lived in Wales, he did have various interactions in Wales throughout his life. This special relationship persists on the memorial landscape of the country in various ways, but none as extensive as the Let Paul Robeson Sing! exhibition. This article extends beyond an overview of the exhibition to identify it as an example of exceptional memorialization techniques. Combining the concepts of participatory, temporary, and mobile memorialization, in order to commemorate Paul Robeson through a sensorial, spatially, and conceptually diverse program, Let Robeson Sing! exhibits memory through a unique and engaging memorial landscape. This article situates the exhibition within the techniques of participatory, temporary, and mobile memorialization, and how the combination of the three provides a unique, effective, and affective form of commemorating Paul Robeson in Wales.
