A revolutionary detail

On the side opposite the commemorative inscription, a chased and repoussé copper cartouche contains the coat of arms of the City of Rouen, which testifies to the eventful history of France and the strategic significance, during the French Revolution, of the abolition of symbols of the Ancien Régime.
The paschal lamb, symbolising the City of Rouen, was originally surmounted by the royal emblem: the fleur-de-lis. This was covered over by the new revolutionary institutions with more neutral symbols: 3 bonfires, evoking the work of firefighters.
