Every year, the Journées du Patrimoine (Heritage Days) are an opportunity to discover all the little nuggets hidden away in our beautiful capital. In addition to the well-known museums and institutions that open their doors free of charge, there are some real gems, some of them unusual and hidden, that you're invited to come and discover over the weekend of September 20 and 21, 2025. With guided tours, walks and workshops, you'll be able to explore little-known Paris in good company!
Just off the Parc Monceau, a private mansion houses one of the capital's most discreet museums - that of Pharmacy! Built by Gaston Menier, grandson of the founder of the pharmaceutical drugstores and later of Chocolats Menier, the building now houses theOrdre National des Pharmaciens, as well as a gallery of instruments used at the time, in a small museum well worth the detour. A therapeutic arsenal of 755 jars is still on display, with substances that were supposed to cure diseases, but which we can scarcely imagine being used today!
The mansion's architecture is exceptional, with a beautiful Norman-Moorish pavilion, the only one of its kind in the capital. And let's not forget the period staircase, with its black woodwork and shimmering mosaics depicting the gods of Olympus.
Journées du Patrimoine 2025: the program at museums in Paris and the Île-de-France region
During this 2025 edition of the Journées du Patrimoine, a large number of museums and art foundations are opening their doors free of charge in Paris and the Île-de-France region. Join us on Saturday, September 20 and Sunday, September 21, 2025, for a program full of wonderful discoveries. [Read more]
For the 42nd edition of the European Heritage Days, the Ordre will be offering visitors a tour of its museum, subject to registration. You'll discover the history of the profession through its collections, and in particular the Menier droguier, which brings together the essential drugs of the therapeutic arsenal in nearly 800 blown-glass jars. The tour will also look at the institution's architectural heritage, reflecting the eclecticism of the private mansions built at the end of the Second Empire. These buildings bear precious witness to an era and a way of life in which leisure and entertainment occupied a privileged place, as evidenced by the Folies Ruysdaël theater.
