 The generally accepted interpretation of the name Zweikirchen (modernized form) holds that originally, a church stood in Allweiler itself, while a second church stood out in the countryside as a hub for other villages.To be understood here is that "zwei" is German for “two”.Ernst Christmann interpreted the name Allweiler as "Altweiler" ("alt" means “old” in German), meaning that along with a new hamlet, there was also an old hamlet (this would be "alter Weiler" in modern, everyday German).
