Restoration Day is observed in the canton of Geneva, Switzerland, every December 31. This holiday commemorates the restoration of the Republic of Geneva in 1813, following its annexation by France during the French Revolution. The celebration begins at 8 am with a cannon salute, followed by an official governmental ceremony, a service at St. Pierre Cathedral, and a gala concert also held in the cathedral. The history of Geneva as a republic dates back to 1541, when it was established under John Calvin after gaining independence from the Duchy of Savoy. The republic lost its status during the French occupation from 1798 to 1813, which ended with the departure of Napoleon's army. Restoration Day serves as a reminder of Geneva's rich historical significance and its eventual integration into the Swiss Confederation.
