The Polish Museum in Chicago is an institution whose mission is to collect and preserve Polish national heritage in the United States and to promote Polish culture. The official opening of the museum took place on 12 January 1937, although the idea itself appeared as early as 1928. The Museum's collection includes many valuable works, by outstanding Polish artists such as Olga Boznańska, Leonard Pękalski and Andrzej Pronaszko. From 2018 to 2021, the Polonica Institute funded the conservation of some of the works of the Polish Museum in Chicago.
