The largest work is a stained-glass mural by Pierre Gaboriau and Pierre Osterrath entitled Hommage aux fondateurs de la ville de Montréal (homage to the founders of the city of Montreal).

A plaque by LaPalme and Georges Lauda, commemorating the inauguration of the Metro, is located at the centre of the mezzanine. It is enclosed in a black circular bench, a popular meeting site, referred to as la rondelle (the hockey puck) or la pilule (the pill) or "le banc des fous" (the crazy bench).

The work is a statue of Mother Émilie Gamelin by Raoul Hunter, commemorating Place Émilie-Gamelin (also called Berri Square) in which the entrance is located. The statue is owned by the City of Montreal. The most recent art piece put in place inside the station is the Wall of Peace on the concourse level of the Yellow Line.
