Winona’s Kashubian Cultural Institute and Polish Museum preserves the city’s Polish and Kashubian heritage in a former 1890 Laird-Norton Lumber Company office on Liberty Street. Founded in 1979 after Father Paul Breza acquired the building for materials related to Polish immigrants, it evolved from local community efforts and later broadened its mission to emphasize Winona’s Kashubian identity alongside its Polish roots. The museum presents exhibits on immigrant life, a diocesan collection of church artifacts linked to nineteenth-century Polish Catholic life in the United States, and cultural programming. Its expanded campus and exchanges with Bytów, Poland, reflect Winona’s long-standing identity as the Kashubian Capital of America.
