While the two villages were nominally united as of 1558, only in the course of the 18th century did they finally grow together, all the while recovering from the various wars’ ravages. During the Middle Ages, Berschweiler had been held to be the more important village, but now Wiesweiler was gaining in importance. 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 Glan drives a camerally-hereditary mill on its right bank. Through Bersweiler also runs the road leading from Mainz by way of Kreuznach, Meisenheim to Zweibrücken and into Lorraine, which is why a toll is imposed in the village.”
