European Archaeological Park of Bliesbruck-Reinheim
The European Archaeological Park at Bliesbruck-Reinheim, in the German municipality of Gersheim (Saarland) and the French municipality of Bliesbruck (Département Moselle), is a cross-border project which combines excavations and reconstructions of Celtic and Roman finds with exhibition and educational facilities. It was created in 1989 as a result of the archaeological work being done on both sides of the Franco-German border.
