The 9th arrondissement of Paris is playing along for the Journées du Patrimoine and, for the occasion, enthusiasts and the curious are taking the opportunity to go on a treasure hunt through the district, which presents itself as an ode to the art of living in Paris. Between grand magasins, iconic venues, and fine addresses, this hub, emblematic carrier of the Haussmannian style, stands as a defining facet of one of Paris’s many faces.
