European Heritage Days 2026: dates, themes and programme

The European Heritage Days 2026 take place throughout France on Saturday 19 and Sunday 20 September, preceded by Friday 18 September, which is reserved for school groups as part of the "Levez les yeux !" initiative. This edition puts forward two guiding threads: the heritage of photography, marking the bicentenary of its invention, and heritage at risk, the European theme inviting us to revive, resist and reimagine.

In Boulogne-Billancourt, as across the rest of the Hauts-de-Seine, the event takes the form of self-guided visits, commented tours, workshops, children's activities and exceptional openings. The full programme, site by site, is published on the official platform of the Ministry of Culture, where it can be filtered by location, by opening times and by accessibility criteria.

One piece of advice: check the listings as soon as they go online, as the most sought-after guided tours fill up within days and some require advance registration by email or through a dedicated ticketing service. Elsewhere, admission is free and access is unrestricted.

The heritage sites to visit in Boulogne-Billancourt

The town holds a richer cultural heritage than one might imagine, shaped by two parallel histories: the artistic energy of the 1920s and 1930s, and the automotive industry that long set the rhythm of local life.

The Musée des Années 30, housed in the Espace Landowski, provides the key. Paintings, sculptures, furniture and architectural documents tell the story of a decade when Boulogne drew in artists, decorators and builders. For the 2026 edition, the museum welcomes visitors on Saturday and Sunday from 11 a.m. to 6 p.m., free of charge and without booking, with flash talks offered as you move through the rooms.

A few streets away, the Musée Paul Belmondo occupies the château Buchillot. Here you follow the career of the sculptor, draughtsman and medallist, father of Jean-Paul Belmondo, through his portraits, nudes and medals. The tours organised during the Heritage Days are free but require compulsory booking with the museum, which makes this one of the first appointments to secure in your programme.

To the north of the town, near the pont de Saint-Cloud, the Musée départemental Albert-Kahn opens its former residence and four hectares of gardens free of charge. A Japanese garden, an English garden, a French formal garden, woodland and meadows follow one another like a series of scenes. The link with the national theme is direct: the Archives de la Planète, a vast collection of early colour images assembled at the start of the 20th century, rank among the most precious photographic holdings in France.

Do not miss the town hall designed by Tony Garnier, the église Sainte-Thérèse with its 1920s concrete architecture, or the modernist villas scattered through the neighbourhood, including Le Corbusier's maison Cook. The municipal archives and several local associations round out this itinerary each year with exhibitions and talks.

Île Seguin, La Seine Musicale and industrial memory

The weekend's other great urban walk heads down towards the Seine. Where the Renault factories once stood, the Trapèze district and Île Seguin now form one of the most widely discussed urban projects in Greater Paris. The Pavillon des Projets serves as the starting point for commented tours such as "Voyage en Industries", which bring together models, archives and the testimony of those who keep the memory alive. Listening walks, sound trails and discoveries of the sculptures installed on the island regularly feature in the programme, often with advance registration.

La Seine Musicale, set at the tip of Île Seguin, completes the loop, and it is arguably the fullest event of these Heritage Days. On Saturday 19 September 2026, from 10 a.m. to 6 p.m., the venue opens its doors free of charge: guided tours, concerts, open rehearsals, a chance to discover the new immersive installation at the SeineLab, a space for experimentation with sound and digital technology, workshops for younger visitors and virtual reality experiences run throughout the day. From 11 a.m. to 6 p.m., circus, dance and music performances take over the public spaces around the building, echoing the monumental works of the open-air contemporary art trail on Île Seguin.

Presented by the Hauts-de-Seine department, this event is open to all and takes place on the Saturday only: put it at the top of your schedule. Pont de Sèvres metro station, a Vélib' station 120 metres away, and a walk along the riverbanks to finish, with views towards Meudon and Sèvres.

Widening the itinerary: Saint-Cloud, Sèvres, Issy-les-Moulineaux

If you are staying two days, venture beyond the town boundaries. The Domaine national de Saint-Cloud, with its terraces and perspectives laid out by Le Nôtre, offers activities that bring the vanished château back to life. In Sèvres, the Cité de la céramique opens its workshops and collections, an ideal outing with children. Issy-les-Moulineaux showcases its military heritage and its more unusual sites, while the Domaine départemental de Sceaux, further south, offers guided tours and activities in its park.

And for those wanting to extend the weekend into the capital, the programme of the city of Paris and that of historic Paris remain around twenty minutes away on metro line 9. All these destinations can be reached with a single transport ticket, without a car.

A well-placed hotel in Boulogne-Billancourt for the Heritage Days

The Bijou Hôtel stands at 15 rue Victor-Griffuelhes, 300 meters from Marcel-Sembat metro station on line 9, a five-minute walk. The T2 tram, Musée de Sèvres stop, is eight minutes on foot and runs directly to La Défense as well as to Sèvres. Buses 42, 126 and 175 serve Marcel-Sembat, lines 171 and 467 stop at Pont de Sèvres, and a Vélib' station, Hameau Fleuri Marché, sits at the foot of the building.

If you are driving, the Indigo car park opposite the hotel is secure and open 24 hours a day. From Orly, take metro line 14 to Châtelet Les Halles, then line 1 to Franklin D. Roosevelt and finally line 9 to Marcel-Sembat. From Roissy Charles-de-Gaulle, the RER B to Châtelet Les Halles followed by the same route works very well.
