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.
For Heritage Days, we'll have the opportunity to go behind the scenes of its most iconic sites. This annual event invites us to a weekend packed with free tours and exceptional openings at the heart of captivating venues of every kind.
