Gilly station was opened on 28 August 1992, although it had been built in the eighties. It was refurbished in 2008 and reopened in its current version on 23 April 2008. One of the walls is adorned with coat of arms of other "Gilly"'s in Europe, while the opposite wall features the lyrics of "El pétite gayole", a song in Walloon language written by Belgian artist Oscar Sabeau.
