Starting in early 2019, Grosbous had intense discussions with its neighbour, Wahl, concerning a fusion of the two communes under the name Groussbus-Wal. An important step in this process was the referendum of June 27, 2021, when the inhabitants of both communes expressed their opinion about the project of merging the two communes. The majority of voters in both communes supported the fusion,[2] which took place in September 2023, after the next municipal elections in June 2023.
