Flag of Geneva

The flag of Geneva is the historical flag of the city and the canton of Geneva and of the city, showing the Imperial Eagle and a Key of St. Peter (symbolizing the status of Geneva as Reichsstadt and as episcopal seat, respectively), in use since the 15th century. 

History
The flag of the medieval bishopric of Geneva showed two golden Keys of Peter in the red field of the imperial Blutbanner since 1293.

The full heraldic achievement of Geneva includes a crest in the form of half a sun inscribed with JHS (for Jesus Hominum Salvator), and a scroll below the shield with the motto Post Tenebras Lux.

The coat of arms of the city of Geneva was adopted as the cantonal coat of arms upon the accession of Geneva as a city-canton to the restored Swiss Confederacy in 1815.
