The Irish moniker is “The Emerald Isle.” The moniker is derived from the vast quantities of green grass and rolling hills that can be found throughout the country.
The moist air and mild environment are responsible for Ireland’s characteristic green fields. Large quantities of green shamrocks cover the Irish countryside. St. Patrick, who is the patron saint of Ireland, is said to have used the shamrock to teach the Holy Trinity to the Celts, according to mythology. Republic of Ireland and Northern Ireland comprise Ireland.
