The Agricultural Museum of The Friends of Old Traditions has been in Grandfontaine in the Porrentruy region since 1999.

The Amicale des Vieilles Traditions (Friends of Old Traditions) seeks to keep agricultural traditions alive and to preserve old work vehicles, machines and tools. It aims to buy and restore old farm implements and to preserve them in working condition.
Housed in a 740m2 exhibition hall made of wood, it showcases animal-drawn farming equipment from 1840 to 1850; a collection of 250 objects; 60 tractors of different brands as well as old implements and machines used from 1900 to 1960.
