Middle Weser Region: The Middle Weser Region (German: "Mittelweserregion" ) includes, in its fullest sense, the land along the Middle Weser between Minden and Bremen.  It lies within the federal states of North Rhine-Westphalia, Lower Saxony and Bremen.  However, the term is often used just to refer to the Lower Saxon part, because of the different political development of the three states and the cooperative associations formed in Lower Saxony some years ago (see below).  The Lower Saxon part of the Middle Weser Region forms the geographical heart of this state.  In the centre of the Middle Weser Region are the towns of Minden, Nienburg/Weser and Verden (Aller).  In the extreme north, the city of Bremen, which is not part of Lower Saxony, has a very important influence on that area of Lower Saxony surrounding it.

Salzgitter: Salzgitter (] ) is an independent city in southeast Lower Saxony, Germany, located between Hildesheim and Braunschweig.  Together with Wolfsburg and Braunschweig, Salzgitter is one of the seven "Oberzentren" of Lower Saxony (roughly equivalent to a metropolitan area).  With 109,142 inhabitants and 223.94 km² (as of 30 January 2004), its area is the largest in Lower Saxony and one of the largest in Germany.  Salzgitter originated as a conglomeration of several small towns and villages, and is today made up of 31 boroughs, which are relatively compact conurbations with wide stretches of open country between them.  The main shopping street of the young city is in the borough of Lebenstedt, and the central business district is in the borough of Salzgitter-Bad.  The city is connected to the Mittellandkanal and the Elbe-Seitenkanal by a distributary.  The nearest metropolises are Braunschweig, about 23 km to the northeast, and Hanover, about 51 km to the northwest.  The population of the City of Salzgitter has exceeded 100,000 inhabitants since its foundation in 1942 (which made it a city ("Großstadt" ) in contrast to a town ("Stadt" ) by the German definition), when it was still called "Watenstedt-Salzgitter".  Beside Wolfsburg, Leverkusen and Eisenhüttenstadt, Salzgitter is therefore one of the few cities in Germany founded during the 20th century.
