[4] Another Kashubian-American activist associated with the Kashubian Cultural Institute & Polish Museum was the writer and educator Anne Pellowski, who was born in Trempealeau County, Wisconsin, but attended high school in Winona and lived there in her retirement.

The first floor of the Museum building[5] contains exhibits and other materials relating to Polish and Kashubian immigrant life in Winona and the surrounding areas.

The Morrison Annex Event Center also features a 165-foot mural illustrating the lives and contributions of Polish and Kashubian immigrant families in Winona.

The second floor of the Museum building is devoted to a collection of artifacts recovered from churches in the Diocese of Winona, such as the Basilica of Saint Stanislaus Kostka.

The collection is extremely extensive and includes statuary, sanctuary furniture, vestments, and other semi-forgotten accoutrements of nineteenth-century Polish Catholicism in the United States.
