The Maison de l'Outil et de la Pensee Ouvriere (Tool and Trade Museum) is located in Troyes, in a Renaissance style mansion, called Hotel de Mauroy. In 1966, the city of Troyes acquired and entrusted this mansion to the Compagnons du Devoir du Tour de France, an association comprising craftsmen and artisans from the Middle Ages up to now. This association has carefully renovated the mansion and has turned it into a museum. 

The museum has a rich collection of over 10,000 tools that were once used for cutting, crafting, and measuring wood by craftsmen, from the 17th to 18th century. Father Paul Feller, a Jesuit priest, is the person who first started to collect these tools since 1958. The museum also displays photos telling the history of logging, sewing, building log houses, making barrels, wheels, and more. Through these tool and photo exhibitions, the museum intends to provide knowledge and arouse the interest of apprentices, craftsmen, amateurs, and many others, about the history and the tradition of craftsmanship in the old days.
