The Heritage Days are a golden opportunity to delve into the capital’s history, treading in the footsteps of crowned heads, nobles, and remarkable personalities, as you step back into an extraordinary past. Between museums, castles and historic monuments, take advantage of the weekend of 19 and 20 September 2026 to broaden your knowledge with engaging workshops or free guided tours in Paris.
If you appreciate the beauty of the Marais district, why not discover the Hôtel de Sully, exceptionally open for the Journées du Patrimoine. Built in 1625 by financier Mesme Galet, this superb townhouse was soon sold to Roland de Neufbourg and François Poussart, who gave it its current structure, between courtyard and garden, overlooking rue Saint-Antoine.
It was purchased bythe Duc de Sully on February 23, 1634, and became the property of his grandson, the second Duc de Sully, on the death of his second wife. An apartment for the duke was built on the first floor, while his wife, Charlotte Séguier, took up residence on the second floor. In the 19th century, the Hôtel de Sully was rented out to numerous craftsmen; it also housed a clinic and even a gymnasium. The duchess's apartments were also occupied by a piano factory.
Since 1974, the Hôtel de Sully has housed the Centre des monuments nationaux. For Heritage Days, it opens its doors to curious minds and history enthusiasts!
