The Vanguardia article explains that what is currently the Maison de la Catalogne (not to be confused with a Left Bank restaurant of the same name), with a role more symbolic than political in the French capitol, will be reconfigured over the coming months and re-emerge as the virgin embassy.)
Post Script: The Vanguardia article did mention, at the end, that the province of Catalonia does have something called "casals catalanes" established in the Mexican capitol as well as in Santiago de Chile. And the report adds that these would likely be the next to follow in the steps of Paris.
