European Archaeological Park of Bliesbruck-Reinheim

The European Archaeological Park at Bliesbruck-Reinheim, in the German municipality of Gersheim and the French municipality of Bliesbruck, 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. Together with archaeological evidence from the Mesolithic Period, the Bronze Age, and the period of the Germanic migrations, the Celtic and Roman finds from the Iron Age bear witness to a history of continuous settlement in the Blies Valley that spans a period of 10,000 years.
