Viking raids in the Rhineland
The area known today as the Rhineland begins at the confluence of the Moselle and the Rhine and ends at Emmerich, where the Rhine divides into the Lek and the Waal to form a delta. In the east, the Rhineland ends close to the Rhine itself, being bounded by low mountain ranges such as the Siebengebirge or Bergisches Land. To the west its boundary is less well defined, but in general parlance it runs beyond the present state border with the Netherlands, i.e. east of the Meuse. Because the modern state of Rhineland-Palatinate lies south of the Moselle, the low mountain range of the Eifel north of the river is usually seen as belonging to the Rhineland. Areas south of the Moselle, such as the Hunsrück, are also considered to be part of the Rhineland.
Rheinwesterwald Volcanic Ridge
The Rheinwesterwald Volcanic Ridge (), or more rarely, the Asberg Plateau ("Asberg-Hochfläche") is a hill ridge and natural region, roughly 13 kilometres long and 3 to 4 kilometres wide, in the north of the German state of Rhineland-Palatinate and south of North Rhine-Westphalia west of the Rhine, which is adjoined in the south by the Siebengebirge. The name was introduced in the late 1950s together with the natural regional major unit of Niederwesterwald.
