Created in 2005, the International Museum of the Reformation (MIR) exhibits living traces of the history of Geneva and the Reformation. Through more than 650 objects, books, manuscripts, paintings, and engravings, the MIR illustrates the specificities of the Reformation, its origin, history, evolution, and the influence it has had on the political, cultural, social, and religious life of Geneva, Switzerland, and beyond.

The MIR is located at Cour Saint-Pierre, in the Maison Mallet built in the 18th century on the site of the Saint-Pierre cloister where the Reformation was voted in Geneva in 1536. Together with the archaeological site, the cathedral and its towers, it forms a unique cultural offering in Geneva: the Saint-Pierre Space.

The museum provides visitors with a selection of audiovisual and educational resources, as well as audio guides allowing them to explore the exhibitions in nine explanatory languages.
