Musée du Barreau de Paris, Legal history museum in 1st arrondissement of Paris, France.

The Musée du Barreau de Paris is a legal history museum in the 1st arrondissement housed in the vaulted cellars of a historic mansion. The collection contains records from major trials, portraits of renowned lawyers, and documents about the development of the French legal system.

The museum was founded in 1983 to preserve documents from major French trials spanning several centuries. The collection ranges from French Revolution proceedings to modern legal cases and shows how justice has evolved over time.

The collection displays how prominent French lawyers documented their work and beliefs through paintings and handwritten records. You can see how attorneys in earlier times preserved their cases and personal convictions.

The museum occupies the vaulted cellars of the Hôtel de la Porte at 25 rue du Jour, near the Église Saint-Eustache. It opens for groups by appointment only, and a guided visit in English can be arranged on request. An entrance fee is charged. The cellars are reached underground, so allow time to find the entrance on the street.

The mansion is named after Antoine de la Porte, a fresh-fish merchant and Paris town magistrate who owned it in the 17th century. The street address, 25 rue du Jour, does not carry his name; the building itself is called the Hôtel de la Porte.
