The Counts of Sponheim enfeoffed Kuno von Pyrmont with holdings and an estate in Lahr in 1438.

Lahr belonged to the “three-lord” high court of Beltheim, which was shared by the Electorate of Trier, Pfalz-Zweibrücken (heirs of the Counts of Sponheim) and the lordship of Metternich-Winneburg-Beilstein (heirs of the Lords of Braunshorn).

The congregation belonged to the parish of Lütz in the rural chapter of Kaimt-Zell and in the archdeaconry of Karden.

The municipality's arms might in English heraldic language be described thus: Gules in dexter base a plough argent and in chief sinister a cross-staff bendwise surmounted by a sinister ear Or, on a chief of the second a cross of the first.

[4] The Hunsrück-Mosel-Radweg (“Hunsrück-Moselle Cycle Path”) runs through the village's outskirts, through the Luhnhofwald (forest).

It is 30 km long and links the town of Kastellaun in the Hunsrück with Treis-Karden on the river Moselle.

In earlier days, housewives did their washing here and then spread the various pieces of laundry out on a nearby meadow to bleach.
