European Heritage Days 2022: shall we drop you off?

European Heritage Days: when the extraordinary opens up to all
Crossing the Île-de-France for a maximum of 4 euros* is good. But crossing the Île-de-France to discover wonderful places usually closed to the public, for a maximum of 4 euros*, is better!
On September 17 and 18, 2022, the 39th European Heritage Days will take place : and this year again, take the opportunity to be amazed - very close to home, or even at the other end of the region, because during these 2 days, several hundred places, often unprecedented, open their doors to you.
Examples of exceptional visits?
- Behind the scenes of the reconstruction of Notre-Dame Cathedral, in Paris (75)
- The National Research Institute for Agriculture, Food and the Environment, in Versailles (78)
- Jean Cocteau's house, in Milly La Forêt (91)
- A railway signal box, in La Défense (92)
- RATP's Chanzy maintenance and signage site in Montreuil (93)
- A geothermal power plant, in Ivry-sur-Seine (94)
- A forge that had not been relit since its closure in 1998 in Herblay-sur-Seine (95)
Two days to marvel... and promoting sustainable heritage
For this 2022 edition of the European Heritage Days, the theme of sustainable heritage has been chosen. The aim is to highlight initiatives that make it possible to reconcile the restoration of cultural heritage and the preservation of natural resources.
A preservation of natural resources that also involves the practice of responsible mobility.
By you, who take public transport, carpool, bike or car-sharing. And by us, Île-de-France Mobilités, by accelerating the introduction of ever cleaner equipment!
