The mill in the village's north end, the oilmill in the southwest and the Naumburgerhof in the west are also part of the older building areas.

The former schoolhouse, in which an ecumenical church service room has now been set up, stands on Hauptstraße (“Main Street”).

[5] Until 27 BC, the area was inhabited by the Treveri, a people of mixed Celtic and Germanic stock, from whom the Latin name for the city of Trier, Augusta Treverorum, is also derived.

That the immediate area was settled in Gallo-Roman times might be proved by a piece of spolia that is today part of a wall in a building at the Naumburgerhof.

These finds were described by the Odenbach pastor Philipp Wilbrand Jakob Müller as follows: “A 3¾-foot-tall tableau chiselled out of fine sandstone; showing three well worked, clad human figures, not hewn into the stone, but rather standing out in a statuelike way, the middle figure was missing its head, which was broken off at the torso.

It must, given the clothing and the whole composition, be explained as a female person, a mother who carries and leads her children with devoted love.

A male lion broken into two pieces, about half life size, lying, resting on his forelegs, holding a sheep’s head between them.

Both animals seem to have stood facing each other at a gateway or portal.”[6] About 600, the lordship of Medard was split from the royal holdings and donated to the Bishopric of Verdun.

Nevertheless, Pöhlmann rather assumed that the Gundeswilre mentioned in the document referred to Gumbsweiler (nowadays a constituent community of Sankt Julian), not Ginsweiler.

In 1444, Frederick III, Count of Veldenz, the last from the Hohengeroldseck family to rule the county, died without a male heir; the county passed to his son-in-law Stephen, Count Palatine of Simmern-Zweibrücken, widower of Frederick's daughter, Anna of Veldenz.

Stephen, combining his lands, created the new County Palatine of Zweibrücken, which in the fullness of time came to be known as the Duchy of Palatinate-Zweibrücken.

All these rights passed in the late 17th century to the Lords of Fürstenwerther, the offspring from Frederick Louis, Count Palatine of Zweibrücken's morganatic marriage to a Meisenheim townswoman, to whom the Elector had transferred the village and castle of Odenbach.

After territorial reorganization, Ginsweiler lay in the Mairie (“Mayoralty”) of Odenbach, the Canton of Lauterecken, the Arrondissement of Kaiserslautern and the Department of Mont-Tonnerre (or Donnersberg in German).

Ginsweiler passed on 1 May 1816 to the bayerischer Rheinkreis, or “Bavarian Rhine District”, the name given the Palatinate once the Congress of Vienna had awarded it to the Kingdom of Bavaria as an exclave.

By the time of the 1933 Reichstag elections, after Hitler had already seized power, local support for the Nazis had swollen to 48.1%.

In the Late Middle Ages, Ginsweiler was very small, indeed at best a gathering of several farms right up until the Thirty Years' War broke out in the early 17th century.

Great growth in population marked the 18th century, though, which can only be explained by newcomers settling in the village, which in the beginning was likely the result of French repopulation measures.

Even today, Roman spolia are to be found on the farm, leading to speculation that such an ancient estate may have lain just here.

[13] From the Early Middle Ages, Ginsweiler belonged to the Glan ecclesiastical chapter and was a branch congregation of the Church of Medard.

After the Reformation was introduced into the County Palatine of Zweibrücken about 1537, all the village's inhabitants had to embrace Martin Luther’s teachings.

Likewise in 1588, a decree from the Count Palatine meant that everyone then had to adopt John Calvin’s Reformed beliefs.

With the arrival of new settlers who had come to repopulate villages emptied of people by the Thirty Years' War, and with the promotion of Catholicism by the French during King Louis XIV’s wars of conquest, the Catholic share of local villages’ populations began to rise.

Another thing that could explain the strong growth in the Catholic population at this time is missionary work being done by the Franciscan convent that had then set itself up in the town of Meisenheim.

[1] The German blazon reads: In gespaltenem Schild rechts zwölffach von Silber und Blau unterteilt, links in Schwarz ein goldener Ginsterzweig.

The municipality's arms might in English heraldic language be described thus: Per pale barry of twelve argent and azure and sable a broom twig slipped palewise Or.

The charge on the sinister (armsbearer's left, viewer's right) side, the broom twig, is canting for the village's name.

The arms were designed by Mr. Becker from Malberg, were conferred by the old Regierungsbezirk of Rheinhessen-Pfalz (whose seat was in Neustadt an der Weinstraße) and have been borne since 13 December 1978.

Further sources of income in the Ginsweiler area were the sandstone quarries, which were shut down after the Second World War owing to unprofitability.

There is also bus route 131, which on working days runs as a direct link from Ginsweiler to Kaiserslautern Central Station.

Together with his wife, a writer, he died in an air raid on Bad Dürkheim late in the Second World War.
