On Saturday September 20 and Sunday September 21, we're taking advantage of the not-to-be-missed event of the 2025 autumn season: we're talking about the European Heritage Days, a major weekend in Paris, the Île-de-France region and even throughout Europe.
So, now's the time to visit our must-see Parisian landmarks, places of power and historic squares, but also to discover little-known, secret places on truly unusual tours. While Paris is THE destination of choice for these Journées du Patrimoine 2025, the rest of the Île-de-France region also has a lot to offer!
In Essonne, the town of Juvisy-sur-Orge is not to be outdone for these Journées Européennes du Patrimoine 2025. And with good reason: this is your chance to (re)discover this small town, stroll through the streets lined with old houses, discover theSaint-Martin church or stroll along the peaceful banks of the River Orge. And don't forget to visit the Parc de la Mairie, or take a picnic to eat on site. It's already shaping up to be a jam-packed program in Juvisy-sur-Orge, on Saturday September 20 and Sunday September 21, 2025!
Church of Notre-Dame de France
The association Les Amis de l'église de Juvisy offers guided tours of the Notre-Dame-de-France church on Saturday and Sunday afternoons. The church is also open to the public on Saturday and Sunday from 9am to 6pm. Information panels are available in the church for self-guided tours.
