The museum explains the concept of special guilds for the building and construction trades, by showcasing the collection of Pierre-François Guillon (1848-1923), a Master carpenter of the guild known as “The Duty of Freedom”. Pierre-François Guillon founded a school for construction design arts in 1871 in Romanèche-Thorins. There he taught carpentry, joinery, and stone work to apprentices, from all over France and from abroad, for 52 years. After Guillon’s death in 1923, his son Osiris donated his father’s masterworks, all the documents and souvenirs of his life as a Master, and all of the School’s students’ documents and models to the department of Saône-et-Loire. The original museum was built in 1928. In 1994, the General Council of the department of Saône-et-Loire had the old museum renovated, and added some new rooms for the permanent and temporary exhibits. The exhibit space is used to display the extensive Guillon collection, which has been expanded through donations, bequests, and acquisitions. An audio guide is available in French, English and German.
