Brittany is a large peninsula in the north-west of France, surrounded by the English Channel to the north and the Atlantic Ocean to the west. Historically, the region is made up of two distinctly different cultural and linguistic areas: Gallo, a Romance language, was spoken in the eastern part (Upper Brittany), while the inhabitants of the western part (Lower Brittany), spoke Breton, a Celtic language. Inevitably, two different cultural traditions and customs came hand-in-hand with the different linguistic traditions.
