Bischofsheim borders in the north on the town of Hochheim (Main-Taunus-Kreis), in the east on the town of Rüsselsheim, and in the south and west on the municipality of Ginsheim-Gustavsburg.
Mainz-Gustavsburg station is the station of the town of Ginsheim-Gustavsburg in the German state of Hesse on the Main Railway from Mainz to Frankfurt am Main.
With the establishment of the present State of Hesse, Wimpfen and Steinbach were separated from the Starkenburg region; in turn, the Bischofsheim and Ginsheim-Gustavsburg quarters of the City of Mainz, located east of the Rhine River, passed to the Groß-Gerau district.
In 1945, the American and French occupying authorities transferred Gustavsburg to American administration and several months later it became part of the new state of Hesse.
