How was Rosa Parks connected to O Museum? O Museum served as the “home-away-from-home” for Mrs. Rosa Parks for nearly a decade through the Museum’s Heroes-In-Residence program. Visitors can step inside the rooms she lived in and learn about her time in Washington, DC and her lifelong humanitarian work
