Provinces of Wallonia 
Hainaut - The most urbanised of the Walloon provinces, Hainaut developed into one of Europe's most important industrial regions in the 19th century. The province is home to historical towns such as Mons, Tournai and Binche as well as post-industrial ones such as Charleroi, La Louvière and Mouscron. The countryside of Hainaut is generally hilly and agricultural, though it is also dotted with woods and traces of its agricultural past (you will, for instance, find a number of boat lifts on its canals). The southern part of Hainaut, around the town of Chimay, is part of the wilder Ardennes region.
Province of Liège - Like Hainaut, the area that is now the Province of Liège developed into one of Europe's most important industrial regions in the 19th century. Before that, the area was part of the Prince-Bishopric of Liège, which was an independent country for over 800 years. This history, which is visible in the city of Liège as well as in numerous smaller towns and villages, still gives the province a very distinct identity. The province also offers its fair share of pleasant countryside, picturesque river valleys and untouched nature, most notably in the High Fens nature reserve. While most of the province is French speaking, the easternmost part substitutes the German-speaking part of Belgium.
