NB: Shown here are the regions that were announced in 2016. Even today many visitors and many of the French themselves are slow to use the new names, preferring the former smaller regions, which are presented here on the right - - >
In January 2016, France saw a major reorganisation of its regions. The original 22 regions were reduced to 13 regions (12 in mainland France plus Corsica). Each of these is subdivided into 2 to 13 departments.
Here are the new regions of France

The former 22 Regions

Many of the former capitals of the old regions have remained the same; however where there has been a change, there is real worry about the diminishing economies of these cities. Losing out are Clermont Ferrand (former capital of the Auvergne), Châlons-en-Champagne (former capital of Champagne), Nancy (former capital of Lorraine), Amiens (former capital of Picardy), Besançon (former capital of France-Comté), Montpellier (former capital of Languedoc-Roussillon), Limoges (former capital of Limousin), Nancy (former capital of Lorraine), Caen (former capital of Lower Normandy), and Poitiers (former capital of Poitou-Charentes).
Alsace in the east, bordering Germany and Switzerland. A region of pretty timbered buildings and a distinct German flavour. Capital: Strasbourg

Auvergne in the mountainous Massif Central. A beautiful, central volcanic region that is largely undiscovered by visitors. Capital: Clermont Ferrand
Brittany is a gorgeous coastal region in the west with dramatic scenery. Less well known is the fact that it has over 4,000 chateaux, manors and medieval homes. Capital: Rennes
