 The village's name, Lohnweiler, has the common German placename ending "—weiler", which as a standalone word means “hamlet” (originally “homestead”).Originally, Lohnweiler was an autonomous parish with a church (the "Nikolauskirche", or Saint Nicholas’s Church), which stood from the Middle Ages until the 19th century.It is certain that this church was built by Count Friedrich II of Veldenz about 1380, and it is highly likely that there had been forerunners to this church.
