Middle Weser Valley
Germany
The Middle Weser Valley (Mittlere Wesertal) is part of the Weser Depression around the River Weser on the North German Plain, extending from the gap of Porta Westfalica to the town of Hoya. It is not a true valley, because it is only bordered by low hills at two points. It lies in the German federal states of Lower Saxony and North Rhine-Westphalia.
