Fraxinus ornus
The arboretum was established in 1994 to protect the former park of the Château des Brasseurs (Brewers' Castle), originally created in 1888 by local brewery owner Victor Champion, who planted a number of trees from North America and Asia when laying out the park. Although Xertigny's brewery closed in 1966 and the château now houses the town government, the arboretum preserves many of the park's old trees, including fine specimens of "Araucaria", "Cladastris lutea", Douglas fir, "Fraxinus ornus", and "Sequoiadendron" (45 meters).
