Düsseldorf-Unterbach
Unterbach was a local borough of Erkrath, Germany, until 1975, when it became an urban borough of Düsseldorf in a local reorganisation. A portion of the pre-1975 Unterbach remains as the borough of Erkrath-Unterfeldhaus. The eastern end of the borough of Düsseldorf-Vennhausen was attached to Unterbach during the reorganisation since it was already culturally associated with Unterbach.
