Dive into the Neolithic for a weekend during Heritage Days in the Paris region! We unveil the program at the Archéosite for September 19 and 20, 2026.

The European Heritage Days are an annual event celebrated in some 50 European countries. Initiated in 1985 by the French Ministry of Culture, they generally take place on the third weekend in September. Their aim is to raise public awareness of the richness and diversity of our cultural heritage, by opening monuments, historic sites, parks, gardens and other heritage sites to the public free of charge, as they are often closed or not easily accessible during the rest of the year.

In Paris, the European Heritage Days are the perfect time to explore the city. Over the weekend, emblematic sites such as the Palais de l'Élysée, the Senate, the Sainte-Chapelle and the Musée d'Orsay open their doors to the public. In addition to these visits, a wide range of events are on offer: guided tours, children's workshops, temporary exhibitions and shows. It's a unique opportunity for Parisians and tourists alike to discover the capital's hidden treasures and gain access to places that are often inaccessible.
