Saint-Maurice parish is represented by the centre of the cross (same shade), which brings together the four churches (the cathedral,
Saint-Pierre-Ville, Sacré-Cœur, Saint-Julien).
The three semicircles represent the golden balls on top of the cathedral's bell towers (same colour).
The range of greens represents the shades of colour of the stained-glass windows, recalling the cross in the stained-glass window of the apse chapel.
