Today, the official coat of arms as used by the government of Gibraltar consists of the original coat of arms with the addition of the motto "Montis Insignia Calpe" ("Insignia of the Mountain of Calpe"; "Mons Calpe" was the Latin name of the Rock of Gibraltar), which was granted by the College of Arms in 1836 to commemorate the 1779–83 Great Siege of Gibraltar. It is the oldest coat of arms in use in an overseas territory of the United Kingdom and is unique in that it is the only armorial insignia that dates from before the period of British colonial administration.
