Journées du Patrimoine 2026 in Paris: 18 exceptional places you cannot miss
A weekend that opens doors which stay firmly shut for the rest of the year: that is the promise of the Journées du Patrimoine, taking place on Saturday 19 and Sunday 20 September 2026 in Paris and the Île-de-France region. This 43rd edition brings together museums, monuments, institutions and rarely seen venues for free visits, activities and enriched programmes.
Republican institutions exceptionally open to the public
Among the most eagerly anticipated highlights, France’s great institutions of state take pride of place. The Assemblée nationale opens its doors on both days, with free-access visits to the Palais Bourbon and the Hôtel de Lassay, available by prior registration only. The Sénat, meanwhile, invites visitors to explore the Palais du Luxembourg, the Petit Luxembourg and the greenhouses of the Jardin du Luxembourg. The Ministry of Agriculture also joins the movement, unveiling the Hôtel de Villeroy, a private mansion in the 7th arrondissement that is normally closed to the public.
These openings are rare. They offer a chance to step inside the spaces of power that most of us pass by without ever entering. Registrations for these visits fill up fast, so it is well worth planning ahead.
Iconic monuments: free entry for this cultural landmark weekend
Paris’s great monuments are also part of the event. The Arc de Triomphe and the Panthéon open their doors free of charge on 19 and 20 September. It is the perfect opportunity to visit without spending a penny and to experience them from a fresh angle, far removed from the standard tourist circuit.
The Basilique du Sacré-Cœur, perched atop the Butte Montmartre, reveals its secrets over the course of the weekend. The Hôtel de la Marine, on the place de la Concorde, also opens on both days. Each of these venues offers a deep dive into the history of the capital, through architecture and heritage seen in a whole new light.
Art, culture and behind the scenes: the places you should not miss
Art and culture lovers have plenty to look forward to as well. The Musée du Louvre exceptionally opens its art workshops on 19 and 20 September, by registration. It is a chance to learn more about the craftsmanship that goes on behind the scenes, as well as to explore the building’s remarkable architecture. Reservations go quickly, so early booking is strongly advised.
The École des Beaux-Arts de Paris also welcomes the public for this edition. The Musée des Arts et Métiers offers free visits and activities, particularly popular with families and children. Finally, the Gaîté Lyrique opens its backstage on Sunday 20 September only, through guided tours available by reservation.

Retail, fashion and transport: an unexpected side of heritage

These itineraries weave together history, architecture and fascinating anecdotes about these iconic Parisian temples of fashion.
The Maison de la RATP opens its Urban Station, the headquarters of Paris’s public transport network. On the programme: simulator driving and a ride on a vintage bus, for a full immersion in the history of Île-de-France transport. The Galerie Dior also takes part in the event, with a programme centred on the world of the Couture House.
Beyond Paris: Saint-Germain-en-Laye and Roissy airport
The Île-de-France region offers equally remarkable destinations. In the Yvelines, Saint-Germain-en-Laye puts on a programme described as fit for royalty for the weekend of 19 and 20 September. The royal town, which has inspired countless artists, plays a full part in the cultural momentum of this edition.
In Seine-Saint-Denis, Paris Roissy-Charles-de-Gaulle airport lends itself to unique guided tours. France’s busiest airport becomes, for the occasion, a heritage site in its own right. Meanwhile, the Lycée Henri IV in Paris opens its doors to reveal this listed historic monument and its medieval treasures.
