The highest point in the outlying countryside is found on the high expanse in the cadastral area "Auf der Platte".

[4] The Ortsteil of Niedereisenbach lies on the Glan's left bank, 172 m above sea level, at the mouth of the Eisenbach, which flows into the community from the west.

The north side of the hollow abuts a foothill of the so-called Kipp, which borders the Glan valley all the way to Offenbach in a broad bow.

The highest point in the outlying countryside is found in the cadastral area "Auf Hardt", which has an elevation of 339 m above sea level.

The shift from a farming village to a residential community with people in various occupations lasted until the 1960s; workers now commute to jobs in Kaiserslautern, Bad Kreuznach, Kirchheimbolanden and Ludwigshafen.

Besides the floodplains in the valley, the landscape is made up of slopes and stony heights, as reflected in some rural cadastral names such as "Auf dem Klöppchen" ("On the Little Knocks"), "Hungergraben" ("Hunger Pits"), "Rosskopf" ("Horse’s Head"), "Weisselstein" (perhaps "Whitewashed Stone") and "Rauweide" ("Raw Grazing Land").

[7] In 1150, Hachenbach had its first documentary mention in a document according to which Archbishop Heinrich of Mainz acknowledged the founding of a monastic cell in Offenbach by the freeman Reinfried von Rüdesheim.

Like many other villages in the region, Hachenbach, too, was utterly destroyed in 1677 in the Franco-Dutch War (1672-1678) by French King Louis XIV's troops.

As before, the cost was split at a ratio of 2:1, between the rightful heirs to the lordships on each side of the Glan, but the total this time was only 850 Gulden.

In the course of administrative restructuring in Rhineland-Palatinate in 1969, Hachenbach was merged with the neighbouring village of Niedereisenbach, which hitherto had belonged to the Birkenfeld district, to form the new municipality of Glanbrücken.

In another document from 23 June 1336, in which Niedereisenbach is named as INFERIORI YSENBACH (nieder – cognate with the English word "nether" – in German and inferior in Latin both mean "lower"), Werner, the archpriest of Kusel, witnessed the building of the chapel consecrated to Saint Valentine at Eisenbach.

In 1358, Clas von Kellenbach pledged the village of Eisenbach, which he held in fief, and the mill to Count Heinrich of Veldenz for the sum of 180 pounds in hellers.

The manor house stood above the Hofpfad (nowadays a street, although the name means "Estate Path") near the Klink property.

After Johan Ludwig von Kellenbach's death on 21 September 1750, the house's heirs and the Duchy of Palatinate-Zweibrücken became embroiled in a years-long court case that ended with the estate being auctioned off.

[15][16] In 1798, Niedereisenbach was declared French territory and passed within the German lands on the Rhine's left bank that had been annexed by France to the Department of Sarre (whose seat was at Trier), the Arrondissement of Birkenfeld, the Canton of Grumbach and the Mairie ("Mayoralty") of Offenbach.

As part of this state, it passed by sale in 1834 to the Kingdom of Prussia, which made this area into the Sankt Wendel district in the Regierungsbezirk of Trier, the Amt of Grumbach and the Rhine Province.

Later, after the First World War, the Treaty of Versailles stipulated, among other things, that 26 of the Sankt Wendel district's 94 municipalities had to be ceded to the British- and French-occupied Saar.

In the course of administrative restructuring in Rhineland-Palatinate in 1969, Niedereisenbach was merged with the neighbouring village of Hachenbach to form the new municipality of Glanbrücken; it was also transferred, this time to the Kusel district, in which it remains today.

It also became part of the Verbandsgemeinde of Lauterecken, and until 2000, when it was dissolved, Glanbrücken also lay in the Regierungsbezirk of Rheinhessen-Pfalz, whose seat was at Neustadt an der Weinstraße.

A 1586 building directory names 14 Rauchhaber (literally "smoke havers", that is, people who have a hearth, and therefore a household) who had to pay contributions in kind.

The following table shows population development over the centuries for Hachenbach, with some figures broken down by religious denomination:[21] Anyone who wanted to settle in Niedereisenbach back in feudal times became a serf of the Barons of Kellenbach.

Other forms of the name that the village (now constituent community) has borne over the ages are Hachinbach and Hachmach (14th century), Oberhachenbach and Niederhachenbach, even Glan-Hachenbach to distinguish it from otherwise like-named places (Sienhachenbach, Schmidthachenbach – each originally likewise hyphenated).

[23] The name Niedereisenbach is made up of the common placename ending —bach, as with Hachenbach, prefixed to which is the word Isen, which unlike many local defining prefixes refers not to a personal name, but rather to the Middle High German word Isen, meaning "iron" (Modern High German: Eisen) or "ore", or even just generally, "metal".

The further prefix Nieder—, which is cognate with the English word "nether", and bears the same meaning, distinguishes it from Obereisenbach, today a constituent community of Sankt Julian, which lies upstream.

At the graveyard "at the steep track" (a translation of the cadastral name "An der Steige"), both denominations buried their dead beginning in 1889.

In 1964, a spiral staircase was built onto the quire tower, giving access to the belfry, which had now been converted into a sitting room.

The church consists of a biaxial aisleless room, joined onto which to the northeast is a reduced, rib-vaulted rectangular quire.

[28] The following are listed buildings or sites in Rhineland-Palatinate’s Directory of Cultural Monuments:[29] The inhabitants of Glanbrücken have since 1992 been holding their kermis (church consecration festival, locally known as the Kerwe) jointly on the first weekend in August.

The Steinbruch-Aktiengesellschaft Köln (a quarrying company from Cologne) located down from the railway station and built a stately administration building.

On the 50-year jubilee of his service, he was awarded the Prussian House Order, and the municipality gave him an upholstered red armchair as a gift.
