M.Chat is the yellow smiling cat created by artist Thoma Vuille, an iconic figure in global urban art. From June 2nd to August 1st 2026, Galerie Laurent Rigail exhibits around thirty works at 1 rue Voltaire, just next to the Saint-Roch church. Free entry, Tuesday to Saturday from 11am to 7pm. Open workshops are also organised every Wednesday and Saturday (10€). It is the kind of accessible, uplifting exhibition that draws very different people into the same space. You do not necessarily come for the art, and you leave with something anyway.
