Initiated by the Atomium Exhibitions Department [Atomium Expo], the Art & Design Atomium Museum is the result of a dual objective. One aim relates to the Atomium’s role as a tourist attraction and a cultural and educa- tional centre. With this in mind, the department was keen to organise exhibitions on a larger scale than the limited space available in the Atomium. The ideal solution was to establish a location in the immediate area around the building. The other aim was to provide the best possible setting in which to display an exceptional design collection [the Plasticarium]. Its former owner [Philippe Decelle] wanted the collection to remain together and to form part of a museum project for Brussels. Launched in the 1980s, this remarkable collection, the only one of its kind in the world, comprises several thousand plastic objects, from the most commonplace everyday items to works of art. The intention behind this project was to create an exemplary type of art and design exhibition. In this way, it forms part of the cultural programme established by the Atomium following its renovation (2006) and its 50th anniversary (2008). What do the notions of modernity and progress – the key words for Expo 58 – mean now, with regard to contemporary creativity, design and architecture?
