The mural "Das Meer" by Max Kämpf, created in 1950, transforms a school facade into a symbolic landscape where education meets the elemental force of the sea. Located above the main entrance, the artwork uses a modified sgraffito technique, with motifs scratched through layers of colored plaster to reveal a white underlayer. This physical process of revealing form mirrors the educational journey of uncovering knowledge. The composition is thoughtfully divided: three allegorical figures representing foundational professions—farmer, merchant, and blacksmith—are stacked to the left, grounding the scene in human endeavor. The dominant green field, however, is an abstracted sea, its surface rendered not with literal waves but with dynamic circles, loops, and swirls. These forms symbolize strength, constancy, and vitality, qualities directly paralleled in the pursuit of learning and skill. Above this vibrant sea, a scattering of modern elements—two birds, an airplane, and a shipping flag—suggests both freedom and navigation, themes essential to a student's path. The artwork thus functions as a permanent, public statement on the school's purpose, connecting traditional trades with the boundless, energetic potential of the mind, all framed within the enduring metaphor of the ocean.
