The double city of Ginsheim-Gustavsburg in the northwest of the Groß-Gerau district in the German state of Hesse, has about 16,000 inhabitants.
The placename is believed to go back to the Frankish Gimmo family and had its first documentary mention in 1211 as "Ginnensheim" in the "Oculus Memorie" (Eberbach Monastery's goods directory).
The constituent community of Gustavsburg owes its name to the Swedish King Gustav Adolf, who in 1632, during the Thirty Years' War had a fort built on the Mainspitze.
Found during work on this was, among other things, a Roman horseman's gravestone, a copy of which now graces the Town Hall's lobby.
A year later, the Nuremberg firm Klett & Co. (which later became MAN-Werk Gustavsburg branch of nowadays Maschinenfabrik Augsburg-Nürnberg, or MAN) began building work on a bridge across the Rhine.
In the years that followed, Kostheim townsfolk who still owned land south of the Main sold their fields to Ginsheim farmers, thus making 1808 Ginsheim-Gustavsburg's actual time of birth.
Thus it remained until the end of World War II in 1945, when the Rhine became a boundary between two zones of occupation, the French and the American, splitting the communities on the Mainspitze triangle away from Mainz and grouping Ginsheim-Gustavsburg and Bischofsheim once again with Groß-Gerau district.
Other things to see include a yacht marina, a local history museum (Heimatmuseum) and an historical industrial crane.
Worth seeing in Gustavsburg are the two churches, the Main Sluice, the Mainspitze and the Cramer-Klett-Platz workers' neighbourhood, which now stands under protection as a monument.
