Architecture is a content area in art education that is not much investigated by art educators. Even less addressed is Romanesque architectural style. Based on direct experiences of visiting hundreds of Romanesque churches in France, Italy, and Spain; many years of teaching design courses; and subsequent research and visual analyses of photos, the author discusses the aesthetic merits of Romanesque architecture through design principles: unity by repetition, variety and contrast, proportion, hierarchical forms, and articulation. Unity, variety, and contrast are found in many modern design books, proportion, less so, but it was very important in the medieval period. Hierarchical forms and articulation are uniquely Romanesque. The author demonstrates that Romanesque builders possessed a great sense of design and creativity.
