On 19 and 20 September 2026, the MGallery collection is opening around sixty of its properties across 26 destinations to the public, for European Heritage Days. Châteaux, listed townhouses and medieval residences: each address offers a bespoke immersion in its history, led by local teams. The initiative illustrates the brand’s positioning strategy, which is built around the heritage and cultural roots of each of its properties.
A heritage event that has become unmissable
Founded more than forty years ago, European Heritage Days give the public access each year to historic and architectural treasures usually closed to visitors. Nearly 20 million French people take part, an enthusiasm that confirms the event’s place in the public’s cultural visiting habits.
For hotel groups that own heritage buildings, the event is also a lever for local visibility, showcasing interiors and stories that day-to-day hotel operations do not always allow them to highlight.
Around sixty properties taking part, in France and abroad
Following a 2025 edition that brought together around thirty hotels, MGallery Collection is nearly doubling its offering for 2026, with around sixty properties taking part across 26 destinations. The brand, which counts more than 120 boutique hotels worldwide, is offering a series of experiences designed specifically for each participating property: musical immersions, culinary workshops or art exhibitions, reflecting the uniqueness of each location and the cultural heritage of its region.
Bookings are required directly with participating properties, as in previous editions, which had already proved highly popular with the public.
A deconsecrated chapel and signature cocktails in Brittany
In the Île-de-France region, the Domaine Reine Margot in Issy-les-Moulineaux, once the refuge of Queen Marguerite de Valois in 1606, is offering several guided tours daily, each followed by a musical moment in its deconsecrated chapel. The property is also organising outdoor tours of its gardens and kitchen garden, complemented by a mixology workshop and a signature cocktail tasting, available as a paid option.
In Vannes, Domaine du Liziec, built around a 16th-century château surrounded by formal gardens and a park of centuries-old trees, is offering guided tours of its grounds led by the property’s management team. The visit ends with a tasting of the signature cocktail Le Jardin d’Eden, crafted from Breton flavours.
In Strasbourg, the Cour du Corbeau is opening its doors to the public for the first time in September. This 16th-century building reveals, during a guided tour, its emblematic raven above the porch entrance, its well dating from 1560, its galleries and its stained-glass windows. Guides share anecdotes about the property’s historic guests, including Frederick the Great, King of Prussia, who wished to meet Voltaire there.
A former artillery riding school and a listed palace in Dijon
In Versailles, the Hotel Le Louis Versailles Château occupies the site of former artillery riding schools built in 1854 under Napoleon III’s Ministry of War. The original gateway, now a listed historic monument, still welcomes visitors today. The building’s interior architecture deliberately respects the height of the neighbouring Château de Versailles, staying to four storeys so as never to exceed the height of the King’s bedchamber.
In Dijon, the Grand Hôtel La Cloche, a listed 1884 building, opens its doors for a guided tour led by the property’s management team. Frequented over the centuries by Lamartine, Napoleon III and Ferdinand de Lesseps, the hotel underwent major renovation works before joining MGallery’s collection of historic addresses.
Carcassonne and the legacy of Albert Robida
In the medieval city of Carcassonne, the Hôtel de la Cité, built on the site of the former episcopal palace, is offering two tours on Saturday and two on Sunday to showcase its history. These tours are followed by a presentation of an exhibition dedicated to Albert Robida, an illustrator, writer and traveller who extensively depicted Carcassonne and its citadel through his drawings and engravings in the late 19th century. At the end of the tour, visitors can continue their discovery in the property’s gardens and on its terrace.
MGallery, a collection built on local roots
Backed by the Accor group, which counts 5,600 hotels in more than 110 countries, MGallery Collection brings together more than 120 boutique hotels worldwide, each inspired by the history of its building or destination. The brand promotes a wellness offering focused on everyday balance and mindfulness, alongside a stated commitment to local artisans and producers in the regions where it operates. Among its best-known properties are the Molitor in Paris, the Municipal in Liverpool, the Santa Teresa in Rio de Janeiro, the Manly Pacific in Sydney, the Athens Capital in Athens and the Arts Saigon in Vietnam.
This heritage initiative forms part of a broader development drive for the brand, which continues its international expansion while showcasing its historic architectural heritage in France.
