[3] Archaeological digs have been undertaken at a number of barrows in the cadastral area known as the Feldmark, up from the Marienmühle (mill), dating from protohistoric times.

Unearthed here were grave goods in the form of remnants of cutting and thrusting weapons as well as a few almost intact pieces of jewellery in typical Celtic ornamental style.

Once running by Horbruch's southern outskirts was the most important overland link between the Roman towns of Augusta Treverorum (Trier) and Moguntiacum (Mainz).

[6] The German blazon reads: In schräglinks geteiltem Schild vorne in Schwarz ein goldenes Horn, hinten rot-silbernes Schach.

The charge on the dexter (armsbearer’s right, viewer’s left) side, the horn, is drawn from Horbruch’s 18th-century court seal, whose original stamp is in private ownership in the municipality.
