The Flag of Montserrat was adopted on 10 April 1909. It is a Blue Ensign with the Union Flag in the canton and the Coat of arms of Montserrat in the fly. The arms feature Erin, the female personification of Ireland, and the golden harp, another symbol of Ireland. This reflects the colony’s Irish ancestry. The Governor of Montserrat uses a Union Flag defaced with the coat of arms.
