To get you into the holiday spirit a special Swedish-style musical event is held in Paris. The event is always held at the Swedish Church (Svenska kyrkan) and most years at a large church in Paris; Paroisse de la Madeleine, Notre-Dame de Paris. The event is a musical Swedish tradition celebrating lightness during the winter darkness.
Update for Paris Plages: Clémence from the Seine-Saint-Denis Office of Tourism contacted me with information in English about the Basin de la Villette section of Paris Plages. Paris Plages takes place in two locations every year: along the Seine (Parc Rives de Seine) and in the Bassin de la Vilette. Bassin de la Villette is the new hoping part of town in the northeastern section of Paris.
Paris Plages began July 8 and continues to Sunday September 3. As they say on the Mairie de Paris’ webpage: “What would summer be without Paris Plages”.
For maps of where to go swimming (baignait) what’s happening along the basin and what’s to eat and drink (rafraîchir et grignoter) visit Que Faire à Paris and about river shuttles, “Bals pop” (popular dance balls), etc. along the Ourcq.
