Duchy of Saxe-Meiningen
The original name of the Pleß was the "Bleßberg". However, because there were two Bleßbergs in the Duchy of Saxe-Meiningen, an "upland" Bleßberg in the vicinity of Eisfeld and this "lowland" one - which often led to confusion – the name was changed at the behest of Duke George II at the end of the 19th century to Pleßberg. A short time later, the suffix "-berg" was dropped.
