The Clarté building was built between 1931 and 1932 on the initiative of the Genevan industrialist Edmond Wanner. The plans for Clarté were drawn up by Charles-Edouard Jeanneret, known as Le Corbusier, and his cousin Pierre Jeanneret. An avant-garde building of 1930’s Geneva, with its sleek silhouette and façades entirely of glass, Clarté was added to the UNESCO's World Heritage List in 2016.
