query: Where is Brittany located?
passage: Brittany
Brittany (/ˈbrɪtəni/; French: Bretagne [bʁətaɲ](listen); Breton: Breizh, pronounced [bʁɛjs] or [bʁɛχ];[1] Gallo: Bertaèyn, pronounced [bəʁtaɛɲ]) is a cultural region in the northwest of France, covering the western part of what was known as Armorica during the period of Roman occupation. It became an independent kingdom and then a duchy before being united with the Kingdom of France in 1532 as a province governed as if it were a separate nation under the crown.
passage: Linguistic boundary of Brittany
The language boundary in Brittany is the language border between the part of Brittany where Breton (a Celtic language) is spoken and the area in Brittany where Gallo (a Romance language) is spoken. The existence of this linguistic border led to differentiate the Celtic-speaking Lower Brittany (West) from the Romance-speaking Upper Brittany (East).
