In Southern Schleswig, the region south of the Danish-German border, a set of original (or, in some cases, reconstructed) Danish placenames exists alongside the German names, just as most North Slesvig placenames have German counterparts dating from the period under Prussian rule (1864–1920). The Danish placenames in Southern Schleswig are used by the local Danish minority and their media, while some in Denmark may avoid using them for political reasons. The use of German placenames in North Slesvig is similarly preferred by the local German minority (when speaking and writing German), but traditionally shunned by many Danes in the region. From 2008, municipalities in Schleswig-Holstein have been allowed bilingual town signs with the official minority languages: Danish, North Frisian and Low German. So far, the city of Flensburg has been the only municipality to introduce bilingual German/Danish signs.
