Wiesweiler lies at an elevation of roughly 165 m above sea level downstream from Offenbach-Hundheim and upstream from the town of Lauterecken.

Predominant are the Quereinhäuser of various sizes, some of which have been expanded into corner houses, with some with the gable facing the street and others with the eaves at the front.

In the more heavily settled Wiesweiler, too, the historical built-up area, made up of great Quereinhäuser and homesteads, comes mainly from the 19th century.

In Roman times, a villa rustica stood where the village now lies, whose foundations were discovered as early as 1855 on the Glan's right bank underneath the mill.

This place, however, belonged to the Waldgravial-Rhinegravial Hochgericht auf der Heide (“High Court on the Heath”).

Thus, Wiesweiler and Berschweiler belonged in the 13th century to two different lordships, but neither to the series of villages around Grumbach, with which Sponheim-Starkenburg and the Duchy of Palatinate-Zweibrücken were enfeoffed in 1363 and 1443 respectively.

A 1336 document states that Wiesweiler was then a Veldenz fief of the knight Emich vom Steine and his wife Hildegunt.

In 1381, the record holds that Peter Hubenriß von Odenbach had received in Wiesweiler – but together with Berschweiler – half the late Emich vom Steine's fief from Count Heinrich III of Veldenz (1378–1389).

Accordingly, Wiesweiler and Berschweiler were in the Late Middle Ages Veldenz holdings, sometimes together and sometimes asunder, and they were repeatedly granted as fiefs to the Waldgravial Knights vom Stein (“of the Stone”) and the family Hubenriß von Odenbach.

Wiesweiler alone was for a short time also a Veldenz fief held by the Lords of Oberstein and the family Fust von Stromberg.

Since the Counts Palatine of Zweibrücken were Wiesweiler's supreme fiefholders, there was no basis in law for this sale, and therefore in 1558, Waldgrave and Rhinegrave Philipp Franz forsook his rights and claims in Wiesweiler in favour of Duke Wolfgang of Zweibrücken, but Philipp Franz's loss was offset somewhat by Wolfgang's payment of an indemnity amounting to 500 Gulden.

Nevertheless, the nearby residence town of Lauterecken offered the villagers shelter during the Thirty Years' War.

There then arose a dispute over it as to whether it – along with the villages of Wiesweiler and Berschweiler – should pass to the Electorate of the Palatinate or the Duchy of Palatinate-Zweibrücken.

First, the Duchy, which then was ruled by King Charles XI of Sweden, took the Ämter of Veldenz and Lauterecken and the Remigiusberg into its ownership.

A permanent solution to the dispute came only in 1733 in the so-called Succession Treaty of Mannheim, which resolved the situation in the Electorate of the Palatinate's favour.

Johann Goswin Widder wrote in his 1788 work Geographische Beschreibung der Kur=Pfalz: “These two places together make only for a slight village.

They lie on the Glan half an hour upstream from Lauterecke to the south, Bersweiler on its right side and Winsweiler on its left.

Neither from the one nor from the other does one come across reliable, older information, leading to the presumption that such primarily only small hamlets as these, subservient to Castle Lauterecke, have since grown into one village community.

The village belonged to the Canton of Grumbach and the Mairie (“Mayoralty”) of Offenbach, as well as to the Arrondissement of Birkenfeld and the Department of Sarre.

As part of this state, it passed in 1834 to the Kingdom of Prussia, which made this area into the Sankt Wendel district.

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 Saarland.

Other names that the village has borne over the ages are Winsswilr (1393), Wyneswilre (1415), Wensewilre (1436), Winzewiller (1445), Wenßwiler (1477), Wentzweiller (1535) and Winßwiller (1578).

The placename ending —weiler is one that is quite widespread, and the prefix most likely comes from an early settler – possibly the village's founder – named Winso.

Other names that the village has borne over the ages are Berswijlre uf dem Glane bi Winsewijlre (1366), Bersswilr (1393), daz gerichte zu Berßwilre (1411) and Berschweiller (1581 and 1643).

From the analysis of the placename ending —weiler and the prefix Berni—, it would seem that the place must originally have been settled by a man named Berni.

The lower field refers to the two once separate communities that grew together to form the current municipality, Wiesweiler and Berschweiler.

The stylized flower on the dexter (armsbearer's right, viewer's left) side stands for the quarryman's (according to the municipality's website) or stonemason's (according to regionalgeschichte.net) trade, once common in the Ortsteil of Wiesweiler.

The black cross on the silver lozenge (diamond shape) on the sinister (armsbearer's left, viewer's right) side represents the foundation of a churchtower built upon an ancient Roman place of worship in the Ortsteil of Berschweiler.

By the late 19th century, the wool weaving cottage industry could no longer keep up with competition from textile mills.
