Isolation
Brittany, the region in the northwestern corner of present-day France, was settled with Britons and Gauls. The Celtic tradition survived in the region since it was isolated from the rest of France, and a lot of festivals and events can trave their origins back to Celtic times. A lot of French “Bretons” also happen to wear traditional Celtic hats called coiffes (meaning “hats of lace”), and about one-quarter of the region’s residents speak Breton, a Celtic language that’s similar to Welsh.
