Building started on the Sauvenière Public Baths and Spa in in 1938. It is a symbol of the Belgian modernist style of the interwar period. Inaugurated in 1942, during German occupation, the baths remained open until 2000. In 2014, they had new life breathed into them when they were designated to house the Cité Miroir. It is now a cultural centre, dedicated to history, dialogue between cultures and citizenship. It proposes temporary and permanent exhibitions. The grand hall was preserved as part of the restoration. It measures 80 metres long and is occupied by two pools which are used as exhibition spaces.
