Brittany (French Bretagne, Breton Breizh, Gallo Bertaeyn) is a peninsula in north-west France, bordering the English Channel on the north and the Bay of Biscay on the south. It is also an administrative région of France. The historical capital was Nantes, but the modern capital of the region of Brittany is Rennes.
The département Loire-Atlantique (including the city of Nantes) was historically part of Brittany, but is now part of the Pays de la Loire region. A movement exists to transfer Loire-Atlantique back to the region of Brittany.
