Lorraine is one of the 26 régions of France. It is the only administrative region with two cities of equal importance, Metz and Nancy. Metz is considered to be the official capital since that is where the regional parliament is situated. The region's name is derived from the medieval Lotharingia.
Lorraine is the only French region to have borders with three other countries: Belgium (Wallonia), Luxembourg, and Germany (Saarland, Rhineland-Palatinate). It also borders the French regions of Franche-Comté, Alsace, and Champagne-Ardenne. The location of Lorraine led to it being seen as a strategic asset and as the crossroads of four nations, it had a very important role in European affairs. Many rivers run through Lorraine, including Moselle, Meurthe, and Meuse.
