The monument is a sculpture by Finnish artist Eila Hiltunen titled Passio Musicae and was unveiled on September 7, 1967. The sculpture won a competition, organised by the Sibelius Society, following the composer's death in 1957. The competition took two rounds after one early winner was abandoned. Originally it sparked a lively debate about the merits and flaws of abstract art and although the design looked like stylised organ pipes it was known that the composer had created little music for organs. Hiltunen addressed her critics by adding the face of Sibelius which sits beside the main sculpture.
