Not to be confused with the neighbouring country of the same name, the province of Luxembourg is the southernmost province of the Belgian region of Wallonia. It is the country's largest province, as well as its least populated one - with only 270,000 inhabitants, as the natural Ardennes region occupy a large part of its territory. The southern part of the province - the Gaume - is part of the Lorraine region, which also contains the French cities of Thionville, Metz and Nancy.
