Flanking the Franco-German border about 25km southeast of Saarbrücken in the charming Blies Valley, the Europäischer Kulturpark Bliesbruck-Reinheim showcases the ruins of a 1st- to 4th-century Gallo-Roman crafts town. Most of the artisans' houses, with their ovens, cellars and heating systems, as well as thermal baths, are on the French (Bliesbruck) side, but the area's most spectacular discovery, the tomb of a Celtic princess from 400 BC, was unearthed on the German side. Her dazzling gold jewellery can be seen at Saarbrücken's Museum für Vor- und Frühgeschichte.
