March 17th of every year is a National Holiday in Ireland. Irish people celebrate their patron saint, St. Patrick. Patrick brought Christianity to numerous Irish people. A tradition on this day is to wear the colour Green and to display a shamrock. The shamrock is the national emblem of Ireland. It is a three leafed plant, that St.Patrick used to explain the Blessed Trinity to the Irish race.
