Poster of Brest: enjoy the wall map of Brest, Brittany, at the most western end of France! Brest is a major natural and military French harbor ideally located on a natural bay at the mouth of Penfeld River. This map is honestly one of the best you can dream of! You'll spot Plougastel, Roscanvel or Lanvéoc at the opposite side of Elorn River and the very peculiar, craggy geography of this place!
