The Heritage Days return on 19 and 20 September 2026 for a 43rd edition rich in discoveries. This unmissable event invites the curious and enthusiasts to explore exceptional venues, little-known treasures and behind-the-scenes spaces usually closed to the public. In Île-de-France, this major cultural gathering highlights historic buildings, but also institutions that embody civic engagement.
Among the program’s standout visits are tours of the Paris headquarters of the Croix-Rouge, housed in the heart of the Hôtel Dieulafoy. Born in 1864 at the initiative of Henry Dunant after the Battle of Solferino, the French Red Cross has traced more than a century and a half of history at the service of those in need. Based on Rue Didot, the national headquarters now coordinates the work of thousands of volunteers and caregivers across the country.
Built in 1895 by architect Émile Vaudremer—who also gave us Buffon High School and Notre-Dame d'Auteuil—this structure was designed for Marcel and Jane Dieulafoy, a pair of archaeologists and explorers. The building embodies late 19th-century constructive rationalism, revealed in its clean, functional lines, tempered by touches of neo-Gothic and medieval flair.
Bequeathed in 1920 to the Society for Aid to the Wounded Soldiers (the precursor to the Red Cross), the townhouse served as a presidential residence before becoming the beating heart of Parisian volunteers. Today, the site hosts teams in charge of first aid, training, and emergency social assistance across the capital.Discover now the detailed programme planned for this weekend of exceptional open doors.

Guided tour of the Dieulafoy Hotel, headquarters of the Territorial Delegation of the Red Cross in Paris
The Dieulafoy House is a private mansion designed in 1895 by the architect Emile Vaudremer (a Parisian architect known for Buffon High School, Notre Dame d'Auteuil, the Santé Prison ....) for Marcel and Jane Dieulafoy, renowned orientalist archaeologists. Come discover its distinctive architecture, straddling late 19th‑century rationalism and Gothic inspirations.
Also immerse yourself in the many interwoven stories this hotel has hosted: the tale of the Dieulafoys, two remarkable figures at the heart of Parisian society in the early 20th century—passionate about heritage and major art enthusiasts—along with the history of the various Red Cross movements of the era to which they contributed, through a collection of objects and historical photos.
Bequeathed to the Society of Aided Military Wounded (the predecessor of the Red Cross) in 1920, it became the residence of its President, before being taken over by the Territorial Delegation of the French Red Cross in Paris. You will then discover the current work of the French Red Cross in Paris (relief, social action...).
Several guided tours of the site will be organized over the course of the weekend.
