The Marine Institute is headquartered at Rinville, near Oranmore, County Galway on the west coast of Ireland.
Though other squadrons were disbanded after the armistice, 105 Squadron continued on duties in Ireland until 1 February 1920, when the squadron was disbanded by being re-numbered to 2 Squadron at Oranmore.
In March 1642 the town, Oranmore, joined Confederate Ireland in a rebellion, against which the owners of the castle, the Marquess and the fifth Earl Clanricarde, held out.
