The Heritage Days offer a chance to join truly unique tours. Beyond the numerous museums or monuments, you can also explore places that are typically closed to the public during this annual event. For example, the courtrooms of the very exclusive Paris Commercial Court, and all this free of charge. In 2026, the 43rd edition of the Heritage Days will be held on Saturday, September 19 and Sunday, September 20.

The visit is an opportunity to discover the history of this building, constructed at the end of the 19th century (between 1860 and 1865) under the reign of Emperor Napoleon III. The tour takes in the courtrooms, decorated in the spirit of the decorative arts and style of the period, as well as the corridors of the Presidency, where the names of every judge since 1564 are engraved.
