American Swedish Institute, Minneapolis

Swan Turnblad, a Swedish immigrant and self-made millionaire publisher, built this mansion but he and his family lived in it only a short time. Swan and his wife, Christina, found it to be too ostentatious for their tastes, so they moved to an apartment across the street. The house, which is on the National Register of Historic Places, has 33 rooms furnished with antiques. After Swan's death, his family founded the American Swedish Institute and donated the house to serve as its headquarters. The museum features rotating exhibits on 150-plus years of the Swedish immigration experience.
