During the Journées du Patrimoine, get off the beaten track and take advantage of the exceptional openings of museums, monuments, institutions and unusual places, on September 20 and 21, 2025! Over the course of a weekend, explore the capital in search of the most beautiful architecture, the greatest mysteries and anecdotes, which your guides will be delighted to tell you about during tours and workshops, many of which are free of charge!

18 meters above the Capucins underground quarries, ancient galleries 1.2km long, exploited between the 12th and 17th centuries (not open to visitors this year), you'll find theCochin hospital and the Port-Royal cloister, part of the former Cistercian abbey, where you can learn about the history of Jansenism and the reign of Louis XIV. This magnificent building, now part of the Hôpital Cochin, is full of anecdotes...

Founded in 1780 by Jean-Denis Cochin, parish priest of Saint-Jacques-du-Haut-Pas, the Saint-Jacques hospice was originally intended for the neighborhood's poor and workers, but continued to expand over time. In 1784, after the closure of the Capuchin novitiate, part of the building was used as a hospital for adults suffering from venereal diseases, first under the name of Hôpital des Capucins, then Hôpital du Midi.

The two establishments successively merged with the Ricord hospital, the Port-Royal maternity hospital, the Baudelocque clinic and the Tarnier hospital. Associated with the hospital since the 1980s, there has been a biomedical research institute, theInstitut Cochin , reorganized in 2002 as a joint research structure in genetics, molecular biology and cell biology. Hôpital Cochin is now a hospital of the Assistance publique - Hôpitaux de Paris, part of the Université Paris-Cité medical faculty.
