Bonjour...
Normandy is north west of Paris....
North East of Paris is going to be "Le Nord-Pas de Calais"
Really North West will be "La Bretagne" (Brittany)
So it's just in between......
Normandy is sort of a triangle begining in Rouen up to Dieppe, Le Havre, then Deauville (quite famous for it's American Fim Festival and known as the "Parisian Riviera") , Trouville... till the Cotentin peninsula .... called as well as the Cherbourg peninsula....
