The community lies in the Westerwald east of Koblenz on the edge of the Nassau Nature Park. The village is characterized by agriculture and commuters to the nearby greater centre of Koblenz. The community belongs to the Verbandsgemeinde of Montabaur, a kind of collective municipality. Its seat is in the like-named town.
In 1198, Simmern had its first documentary mention as Sevenburnen.
Politics
Community council
The council is made up of 17 council members, including the extraofficial mayor (Bürgermeister), who were elected in a municipal election on 13 June 2004.
The wavy embattled (in the heraldic sense) pale with seven battlements in the community's arms refers to the placename Simmern, whose original name of Sevenburnen can be taken to mean “seven springs, wells, cisterns”. The red cross refers to Simmern's allegiance to the Electorate of Trier until 1803 and the golden lion to its allegiance to the Duchy of Nassau from 1815 to 1866.
