Altstadt (German: [ˈaltˌʃtat] ) is the German language word for "old town", and generally refers to the historical town or city centre within the old town or city wall, in contrast to younger suburbs outside. Neustadt (new town), the logical opposite of Altstadt, mostly stands for a part of the "Altstadt" in modern sense, sometimes only a few years younger than the oldest part, e. g. a late medieval enlargement.
