The idea for a monument to a Polish national bard Adam Mickiewicz was put forward by university youth on the account of the return of his remains from Paris. In the years 1882-1888, a committee was set up to conduct a public competition for its design. Teodor Rygier, who took part in all three stages of the contest, was awarded the rights for its production by popular demand, ahead of over 60 artists including the renowned Cyprian Godebski, professor at the Imperial Academy of Arts in St. Petersburg from Paris, who won the first prize. The unveiling of the statue took exceptionally long time due to endless requests for revisions coming from the artistic committee. The monument was finally unveiled on 16 June 1898 for the 100th anniversary of Mickiewicz's birth. The monument design is conventional for its time. The poet, raised on the pedestal, four symbolic groups are on the base: Motherland i.e. Poland, Science and learning – an old man with a boy, Poetry, and Patriotic love or Valour. All bronze figures were cast in the Nellich foundry in Rome. Aside from his statue of Adam Mickiewicz at the Main Market Square in Kraków, there is also one in the Old Town district, namely the bust of painter Juliusz Kossak featured in front of the Palace of Art at Planty Park.
