The mural that adorns the front facade of the school building is an important and easily recognizable aspect of the school itself. Designed by Heinz Gaugel, it measures 44 feet by 66 feet and stands five stories high. The dominant feature of the mural is the two hands, because the artist believed that "education is only worthwhile if the hands are used to transform it into something". The remaining images reflect aspects of ancient cultures, modern technology and nature. The connection between education and all around us is prominent.
Inside the school, the main foyer shows two more murals which represent the vocational studies that formed the original foundation for the school's program. The theme of the mural is continued as the school's yearbook is appropriately titled "The Mural", indicative of all the small pieces that make up the whole school community.
