Southwards, the town stretches into the valley of the river Selz, which empties into the Rhein in the constituent community of Frei-Weinheim or Ingelheim-Nord ("North").

The constituent communities of Ingelheim-Mitte and Ingelheim-Süd ("Middle" and "South") are nestled against the corner of the so-called Mainzer Berg [de] ("Mainz Mountain").

An obelisk on the south side of the village in direction Wackernheim, marks the road begun by Charlemagne, and completed by Napoleon.

[4] Ingelheim is currently divided into six Stadtteile: Ingelheim-Mitte, Ingelheim-Nord, Ingelheim-Süd, Sporkenheim, Groß-Winternheim and Ingelheim-West.

Like all Rhenish Hesse, Ingelheim, too, is sheltered from the weather by the Hunsrück, the Taunus, the Odenwald and the Donnersberg, thereby limiting the yearly precipitation to only 560 mm.

Late 19th century Ingelheim was the residence of the Dutch writer Multatuli (Eduard Douwes Dekker).

In 1939, the formerly self-administering municipalities of Nieder-Ingelheim, Ober-Ingelheim and Frei-Weinheim were merged into the Town of Ingelheim am Rhein.

The five Protestant parishes of the EKHN belong to the Provostship (Propstei) of Mainz, and within this to the Deanery of Ingelheim.

Besides these, the Baptists, Religious humanists and Muslims each have small communities in Ingelheim, as do the Jehovah's Witnesses and Buddhists.

Ingelheim has a multi-purpose culture centre, named kING, located close to the station.

On show are small archaeological finds, objects from architectural sculpture and a demonstrative model of the once imposing building.

All together, the town counts four Carnival clubs: The town has at its disposal a range of historical buildings worth seeing: In the cadastral areas of Nieder-Ingelheim and Frei-Weinheim, mainly north of the Autobahn along Konrad-Adenauer-Straße, but also south of the Autobahn – even within the Boehringer Ingelheim industrial lands – are found drifting chalk sands.

Municipal building uses in drifting chalk sand areas are therefore routinely excluded or only approved in very special cases.

A babysitter exchange, handicraft classes, breakfast and lunch, housework and holiday support are regularly offered, as well as courses and events covering every family theme from babies to health to creativity.

The constituent communities and the surrounding municipalities are served by city and regional bus routes of Omnibusverkehr Rhein-Nahe GmbH.
