Because it is near the Frankfurt Rhine Main Region, the municipality is also a bedroom community and therefore has many new development areas and new citizens.

At the battlefield near Ottenheim, as Gau-Odernheim was then known, at the boundary of the divided land, a so-called stone Sühnekreuz (“atonement cross”) was put up.

In 1286, Rudolf von Habsburg, the King of the Romans, granted Gau-Odernheim Imperial town freedoms.

The master craftsman Erhart Falckener, who was known for his Late Gothic church furnishings, lived in Gau-Odernheim, according to a signature on a work from 1510.

In 1938, the municipality prided itself in “having been the first place in Rhenish Hesse in which Adolf Hitler’s idea had already gained a foothold in the years 1923 and 1924, and wherefrom it was spread into the nearer and further environs”.

The charge remained essentially unchanged until the 17th century when it was replaced with the Imperial eagle, but in 1698, the old composition was restored, albeit this time with a female figure as a supporter behind the escutcheon, no longer seen in the current arms, which have been borne since 1961.

The arms shown on the municipality's own website, and at Heraldry of the World, show the king with silver hair.

In the Nachrichtliche Verzeichnis der Kulturdenkmäler Rheinland-Pfalz für den Landkreis Alzey-Worms, in which the state lists the district's cultural monuments, the following monuments can be found in Gau-Köngernheim:[9] In the vineyards on the Lieberg in Gau-Odernheim can be found the greatest assemblage of wild tulips north of the Alps.

For blossoming time in late April, the local conservation group stages the Wildtulpenfest (“Wild Tulip Festival”) each year on their Natur-Erlebnis-Platz (“Nature Adventure Square”).

Over a former stretch of railway track in Gau-Odernheim's municipal area in 2005, a local road bypass was built.
