 Rehweiler's "Ortsteile" are Rehweiler (on the Glan's left bank) and Reichartsweiler (on the Glan's right bank).Although the merger took place 400 years ago, the two centres are even today clearly distinguished from each other.Rehweiler's two formerly separate parts, the former municipality of Reichartsweiler and the original Rehweiler, can still be made out separately even today.
