For this year's Journées du Patrimoine, the Musée archéologique du Val-d'Oise is offering tours and workshops for young and old on Saturday September 20 and Sunday September 21, 2025. Created in 1983, the archaeological museum conserves over 35,000 objects, and exhibits 3,000 of them, offering a journey from prehistory to the present day.
Sculpted blocks from a 2nd-century sanctuary, concrete statues from the Soviet pavilion built for theExposition Internationale des Arts et Techniques de la Vie Moderne... These are just some of the historical objects that visitors can admire during their visit to the museum.
For the Journées du Patrimoine (Heritage Days), you can take advantage of a whole host of good ideas and unusual events in every corner of the Île-de-France region. You can find ideas for visits close to home, or take advantage of the opportunity to explore the region's heritage. If you'd like to explore the Val d'Oise a little further, here's a guide to what's on in the 95 département to round off your weekend.

### Exhibition
### 40 years of archaeology in Val-d'Oise
### September 20 to December 28, 2025
The Service départemental d'archéologie du Val d'Oise (SDAVO), created in 1984, has been responsible for numerous archaeological digs and discoveries in the Val d'Oise, from the Palaeolithic to the present day.
This exhibition traces its development and answers a number of questions frequently asked by the public: Why dig in this place? What happens to the archaeological remains afterwards? What are the most frequent and rare finds?
The exhibition takes a playful look at the practice of archaeology, before focusing on some of the archaeological discoveries made since the early 1980s.

### Flash visit to the exhibition Agatha Christie, In Search of Archaeology
Agatha Christie, famous for her detective stories, was also passionate about archaeology. Alongside her archaeologist husband, she explored the Middle East, which became a source of inspiration for her novels such as Murder in Mesopotamia, Death on the Nile and The Crime of the Orient Express.
This captivating exhibition takes you on an adventure to discover this aspect of the author's life, which is rooted in the Agatha Christie archives.
An exhibition designed by Vesunna | Site-musée gallo-romain la Ville de Périgueux, and adapted by MADVO.

### Digging Diary
Sunday, September 21, at 3pm (40 min)
Journal des fouilles is a short form about Jane Dieulafoy, the French archaeologist who discovered the site of Susa, in Persia (now Iran), at the end of the nineteenth century. She documents her research in books, drawings and photographs. Initially tracking the influence of Eastern art on European Gothic, Jane and her husband Marcel unearthed the Lion Frieze from the palace of Darius I (522-486 BC), the Ramp of the Staircase from the palace of Artaxerxes III and the Archers Frieze, which they brought back to the Louvre, where they have been exhibited in the Dieulafoy rooms since 1886. Jane Dieulafoy was also a novelist, journalist and photographer. Intrepid and combative, she dressed as a man during the 1870 war, then for excavations in Iran; she kept the male costume on her return to Paris, where she obtained a cross-dressing permit. The show takes spectators into the explorer's bivouac in the middle of the Persian desert.

### Sensitive lesson
Sunday, September 21, 4:30 pm (1h30)
On the occasion of the European Heritage Days, in the museum setting, the soundinitiative ensemble weaves a sensitive dialogue between the crafts of yesterday and the music of today. Each piece resonates with the site, the collections and the tools, like a living echo of buried know-how, inhabited silences and the memory of hands.
