The nineteen-acre Shorewood High School Campus reflects the community’s emphasis on education in the 1920s when the school was first planned. The campus setting was unique in that it resembled a college more than a secondary school. In 1925, the first building was completed. Floodlights have illuminated the football field and athletic track for night events since 1934. By 1938, five more buildings were added. These included an industrial arts building, classrooms for arts and sciences, a physical education center and a gymnasium. The original structure became the school administration building. An auditorium modeled after the RKO Theater in New York City, seating up to 1,300 people, was constructed in 1936. A swimming pool was built in the mid-1970s.

Since 1928, the Shorewood Opportunity School operated from the campus offering evening educational classes and recreational activities for adults until 1970. During the Depression, the Opportunity School developed into a popular community center offering courses in social studies, home economics, the arts and theater.
