INGELHEIM (Ober-Ingelheim and Nieder-Ingelheim), the name of two contiguous market-towns of Germany, in the grand-duchy of Hesse-Darmstadt, on the Selz, near its confluence with the Rhine, 9 m.
Ober-Ingelheim, formerly an imperial town, is still surrounded by walls.
Nieder-Ingelheim has an Evangelical and a Roman Catholic church, and, in addition to wine, manufactories of paper, chemicals, cement and malt.

Thus it was the desire to secure his Jutish kingdom which induced Harold Klak, in 826, to sail up the Rhine to Ingelheim, and there accept baptism, with his wife, his son Godfred and 400 of his suite, acknowledging the emperor as his overlord, and taking back with him to Denmark the missionary monk Ansgar.
Other noteworthy objects in the castle are the fountain in the courtyard, decorated with four granite columns from Charlemagne's palace at Ingelheim; the Elisabethentor, a beautiful gateway named after the English princess; the beautiful octagonal bell-tower at the N.E.
