Which French peninsula contains the city of Brest and projects into the Atlantic Ocean?

The Brittany Peninsula is the French peninsula containing Brest and projecting into the Atlantic Ocean.

Brittany occupies the western part of France, extending into the Atlantic between the English Channel to the north and the Bay of Biscay to the south. Brest is a major naval port on the peninsula’s western coast and is known for its large natural harbour.

The region has a distinct Breton cultural identity, with historical traditions, music, cuisine, and the Breton language alongside French. Its coastline includes rocky headlands, islands, estuaries, and sheltered bays shaped by strong Atlantic tides.

The Brittany Peninsula should not be confused with the Cotentin Peninsula, another French projection farther northeast in Normandy. The Cotentin includes Utah Beach, whereas Brittany contains Brest and the western end of France.
