A landscaped, family-friendly and playful route, to discover the village of La-Rivière-Drugeon and the extinct fibula (brooch dating from the 7th century). A long time ago, a fibula adorned with two dragons was found under the feudal clod that stood in place of the current football field. This jewel brought strength and courage to its owner. No book talks about it, but the appearance of strange phenomena in the Drugeon Valley and especially in the village of La-Rivière-Drugeon leaves no doubt: this object is not lost. Will you be able to unravel the mystery of the missing fibula?
