Stair at the Cluny, Paris

Whitney Warren Jr.'s architectural drawing documents a monumental staircase from the Musée de Cluny in Paris. This cross-section rendering reveals the structural and decorative complexity of 19th-century institutional design, with ornate railings, paneled walls, and carefully articulated spatial relationships. Warren, an American architect trained at the École des Beaux-Arts, employs watercolor and ink to distinguish materials and light. The drawing exemplifies the precision demanded of architectural practice during the Gilded Age, when American architects studied European precedents to establish classical authority in their own designs.
