House Unterbach was probably established in the times of the Carolingian dynasty. Further local historical buildings of Unterbach are mentioned at the former customs office at the eastern local entrance 'at the Zault', the tubing mill and the association house. The columns of the monument bear the names in time-correct sequence in stone. The gallery of the lords of the House of Unterbach and their coats of arms are to be discovered elsewhere in Unterbach on the monument, which also serves as homeland and war memorial. The name of the local part comes from the knights van Unterbeke, whose seat was the House of Unterbach – an old water castle, first mentioned as seat of the knights in 1169. The eastern end of the borough of Düsseldorf-Vennhausen was attached to Unterbach during the reorganisation since it was already culturally associated with Unterbach. A portion of the pre-1975 Unterbach remains as the quarter of Erkrath-Unterfeldhaus. Until a local reorganisation in 1975, it was a part of Erkrath, Germany. Unterbach is a quarter ( Stadtteil) of Düsseldorf, part of Borough 8. Map of Düsseldorf, showing Unterbach (in red) within Borough 8 (in pink)
