The intermediary dome, painted and visible through the opening of the interior dome supports the lantern-turret weighing over five tonnes;

Laurent Dequick, a professional architect, often showcases buildings and architectural heritage in his photos. Here, he goes further by integrating blueprints of each building, these line drawings that represent all of the proportions of the various dots or lines of a figure. “This is the crux of architecture: between the idea and the construction,” he explains. “It all starts with a line, and from the line form must emerge.” It is the search for the perfect harmony of forms, materials, symbols, and uses.”
