Reims Cathedral is a working record of Gothic engineering as much as a religious building, and it names its own engineers inside itself. Construction began in 1211 under the mason Jean d'Orbais after fire destroyed an earlier church on the site, and the building rose gradually over roughly eighty years under a rotating team of master masons; a labyrinth once set into the nave floor recorded four of their names, Jean d'Orbais, Jean Le Loup, Gaucher de Reims and Bernard de Soissons, along with how many years each had worked there, an unusually direct credit for an anonymous medieval craft. Their nave rises thirty eight meters, narrow enough at under fifteen meters wide that the height reads as deliberately exaggerated, carried on flying buttresses that let the walls open into glass rather than stand as solid masonry, the structural trick that makes the whole west front possible.
That front is organized around two features working at different heights. High above the three main portals sits the rose window, roughly twelve and a half meters across, glazed to fill the nave with what Gothic builders themselves called new light rather than the dim interior of earlier Romanesque churches. Below it runs the Gallery of Kings, a horizontal band of giant standing statues added mostly in the fourteenth and fifteenth centuries, dozens of unnamed French monarchs carved at architectural rather than human scale, with Clovis placed at the center of the row as the dynasty's founding figure. Read together, the rose window and the gallery beneath it turn a wall that could have been solid stone into a sequence, light and royal lineage stacked directly on top of each other on the same facade.
