par Discover the magnificent HĂ´tel de Roquelaure at 246 boulevard Saint-Germain in Paris’ prestigious 7th arrondissement, a sumptuous Regency-era mansion that has served as a center of French political power for over two centuries. Built between 1720 and 1724 by architect Pierre Cailleteau dit Lassurance for Antoine-Gaston, Duke of Roquelaure, this architectural masterpiece exemplifies the refined elegance of early 18th-century French design.
Antoine-Gaston, Duke of Roquelaure, was an influential figure at court – first governor of Languedoc and Marshal of France from 1724. The memorialist Saint-Simon described him as “pleasant by profession, extremely worldly,” noting his wit and social grace. His mansion reflected his elevated status, featuring graceful proportions and sophisticated decorations that announced the emerging artistic tastes of the post-Louis XIV era.
The hĂ´tel’s exterior presents a masterful study in restrained Regency elegance. The courtyard facade features a central projection crowned by a triangular pediment, while mascarons (decorative faces) adorn the keystones of the bays. These architectural details demonstrate Lassurance’s skill in balancing classical formality with the lighter touch characteristic of the period.
Inside, the mansion’s refined decorations express the full grace of 18th-century artistic achievement. The vestibule welcomes visitors with trophies and children’s figures, while the dining room features decorations by renowned painter Jean-Baptiste Oudry. Charles Natoire’s paintings grace the small salon and ceremonial bedroom, creating interiors of exceptional artistic merit. In 1733, architect Jean-Baptiste Leroux enlarged the complex, enhancing its grandeur.
After the Duke’s death in 1738, the mansion continued to attract distinguished residents. His daughters sold it in 1749 to Mathieu-François MolĂ©, first president of the Parliament of Paris. In 1808, Jean-Jacques de CambacĂ©rès, Duke of Parma and Napoleon’s Arch-Chancellor, acquired the residence. CambacĂ©rès transformed the hĂ´tel into one of Europe’s most brilliant social centers, hosting sumptuous receptions from 1808 to 1815.
Since 1834, the HĂ´tel de Roquelaure has served governmental functions. It first housed the Council of State, then from 1840 became the Ministry of Public Works. Today, it serves as headquarters for the Ministry of Ecological Transition, continuing its role at the heart of French administration while preserving its remarkable artistic heritage.
The building’s historical and artistic significance earned comprehensive protection in 1961, with facades, roofs, decorative rooms, and gardens all classified as Les monuments Historiques. This recognition ensures that this exceptional example of Regency architecture and decorative arts will continue to showcase French artistic excellence for future generations.
