FIAC stands for “Foire internationale d’art contemporain”—an annual autumn must in the Parisian arts calendar. For its last in-person edition, in October of 2019, the venue was the Petit Palais. Two years on, the 2021 iteration is at the Grand Palais Ephémère (which has been restructured) and showcases 162 international galleries. To complement the fair, an OVR version is also available on the FIAC Web site. Hors les murs? Check out the Jardin des Tuileries, Place Vendôme, and Musée Delacroix. —E.C.
