In 2009, an agreement signed between the La Grandvallière community of communes and the Friends of Grandvaux association allowed the restoration of the Mignot farm while respecting as closely as possible the habitat and way of life of the Grandvalliers of yesteryear.
This restoration benefited from a public subscription within the framework of the Heritage Foundation.
This place has become, every summer, the setting for a temporary exhibition allowing the promotion of the protected heritage.
La Ferme Mignot is a member of the Jura Museums network.
For example, the 2023 exhibition (from July 24.07 to August 15.08) brought back the winters of yesteryear.
On October 6 and 7, as part of the centenary of the birth of Bernard Clavel, a reading stroll from the library led by an actor, based on the work "Murder on the Grandvaux".
