Interesting rural cadastral toponyms in Bosenbach include “Selgut”, which could be interpreted as meaning “Soul Estate” – it might well once have been an endowment to the church in the hopes of securing Salvation – and “Kastellwiese” (“Castrum Meadow”), supposedly a reference to a Roman castrum here, although this is rather doubtful.

Bosenbach has an outlying Ortsteil called Friedelhausen, which was amalgamated with the municipality on 1 January 1971 in the course of administrative restructuring in Rhineland-Palatinate.

Also belonging to Bosenbach is the outlying homestead of Kelterhof, an Aussiedlerhof (farmstead established after the Second World War to enhance food production) built about 1970, but which is now no longer worked as a farm.

In the 18th century, the Lanzenbach drove a small mill, which owing to longstanding disputes with the miller was bought out by the villagers.

Well known is the tower of the former Wolfskirche (“Wolf’s Church”) on the graveyard lands with its paintings from the Middle Ages.

Today in the Wolfskirche tower's stonework, building blocks from Roman times can still be found, some with inscriptions.

A sculpture from Roman times, a lion tearing at an animal that it has caught and a relief can be found in the church's sanctuary.

[6] In 945, Bosenbach had its first documentary mention when Otto I, Holy Roman Emperor, granted his faithful follower Franko a few landholds.

Territorially, Bosenbach belonged to the Imperial Domain (Reichsland) around Kaiserslautern and about 1130, it came to be held as a Palatine fief by the Counts of Veldenz.

Only towards the end of the 16th century did the Duke of Palatinate-Zweibrücken alone exercise this function, using it to force the subjects to convert to the Reformed faith.

During the Thirty Years' War, the Schultheißerei of Bosenbach was abolished and combined with the court region of Eßweiler Tal.

[8] After the new order introduced during French Revolutionary and Napoleonic times, Bosenbach became the seat of a mairie (“mayoralty”).

In the 1933 Reichstag elections, the people of Bosenbach voted 86.3% for Adolf Hitler and his Nazi Party (NSDAP).

The following table shows population development over the centuries for Bosenbach, with some figures broken down by religious denomination:[11] The placename ending —bach (“brook”) is combined in the village's name with the element Baso, which goes back to an early Frankish personal name.

The village has borne the following names over the ages: Basinbahc (945) ; Basinbach (latter half of the 14th century); Basenbecher ampt (1393); Basenbach (1417); Boßenbach (1567); Bosenbach.

The Feldkirche (“Field Church”) outside the village, which had already been standing before the turn of the second millennium, was granted burying rights by 1323.

The Reformed parish of Bosenbach remained in existence on into the Thirty Years' War, and the pastor also had to tend the villages in the Eßweiler Tal (dale).

Owing to the great loss of population, the pastor's post was not filled again until 1671 (23 years after the war's end).

In 1709, ecclesiastical regions were established for the Lutherans in the Oberamt of Lichtenberg, with one with Bosenbach as its hub to which the Reformed followers made their church available.

[1] The German blazon reads: Von schwarz und gold gespalten, rechts über einem gesenkten goldbesäumten blauen Wellenbalken zwei gekreuzte goldene Hämmer, belegt mit dem Zeichen des Planeten Uranus in Gold, links ein rotgefasster und -gedeckter silberner Kirchturm mit gotischem Maßwerkfenster und romanischen Schallöffnungen in schwarz.

[15] The municipality's arms might in English heraldic language be described thus: Per pale sable in chief a Uranus symbol surmounting a hammer and pick per saltire, the whole Or and in base a fess wavy of the second surmounted by a narrower one azure, and Or a churchtower argent with quoins, roof, Gothic tracery windowframes and Romanesque sound holes gules, the window glass of the first.

The churchtower charge on the sinister (armsbearer's left, viewer's right) side is a depiction of the one at the well known Wolfskirche (“Wolf’s Church”) near Bosenbach.

The Uranus symbol on the dexter (armsbearer's right, viewer's left) side recalls the limestone mining in the two centres of Bosenbach and Friedelhausen until 1971.

The wavy fess in dexter base is canting for the placename ending —bach, which in German means “brook”.

During thorough renovations in 1985, a dendrochronological investigation of the roof frame yielded the knowledge that the wood had come from trees felled in 1310.

The masonry in this east quire tower is reckoned to date from the transitional time between Romanesque and Gothic.

This Late Baroque church with its belltower, with the style of spire known as a welsche Haube, presents itself in a good state of repair in Bosenbach's village core.

The other bell was poured in 1746 in Bosenbach and bears the German inscription Jauchzet dem Herrn alle Welt, singet, rühmt und lobet ihn (Cheer the Lord, all the world, sing, praise and laud Him”).

Until the late 19th century, it served the villages of Bosenbach, Friedelhausen and Niederstaufenbach together as a place to bury their dead.

[18] The kermis (church consecration festival, locally known as the Kerwe) is held each year on the last weekend in August.
