In the royal heart of Right Bank Paris, where imperious buildings betray the first arrondissement’s history of housing courtesans and kings, Émilie Briand and Guillaume Multrier found their fantasy home. It’s secreted inside one of the city’s oldest hôtel particuliers, in a coveted village pocket, on the site of the ancient Porte Montmartre — a gate once punching into a five-kilometre stretch of fortress wall built by King Philippe Auguste (1165–1223) to protect Paris from Anglo-Norman invasion. The property came to them through Antonia Rivoire Immobilier, an agent whose unique collection and clientele are captured on the company’s website with a quote from French philosopher Gaston Bachelard: “The home, more than the landscape, is the domain of the soul.”
