Marysville High School is in the Macomb Area Conference of the Michigan High School Athletic Association. Its mascot is the Viking, and its colors are navy blue and white with silver accents.HistoryThe original Marysville High School was constructed in the 1920s and taught grades 6 to 12. It was located at the corner of Huron Blvd. and Michigan Ave. in what was downtown Marysville. In the 1940s, the relatively small school could not accommodate the growing population of the city, caused in part by the opening of the Wills Sainte Claire automobile factory. A new school was necessary, but since this was during World War II, the school board had to petition the U.S. War Department to build the new school. Pictures of the entire student body crammed into a hallway of the old school were sent with the petition. In 1942, permission was granted to construct a new school.The new Marysville High was built adjacent to the original building, which was later known as "the annex". During construction, the basement of the school was reinforced with steel and concrete support beams so it could double as an air raid shelter. The completed school included a gymnasium and auditorium. In later years, the Detroit Pistons held summer practices in Marysville High's gym. In the 1950s and 1960s, a swimming pool, commercial arts, and home economics wing were added.Over the years, Marysville High School underwent more upgrades and renovations, including an addition to the south side of the school in 1979. The property was the former home of the 575-square-foot "annex", which served as the public library until it burned down in 1975. The addition contained 14 classrooms, a band room, and a choir room.
