My friend, Mont-Saint Michel is in Normandy.
For me it's Brittany - it was first stop during my Breizh tour, I found information about it in Brittany Guidebook. I found the breton name "Menez Mikael", lot of breton flags... maybe in historical way Mont Saint-Michel is more breton than norman?
Very nice, looks like Mount St. Micheal in France
a very beautiful piece
