Ireland is a small island in the North Atlantic divided between the Republic of Ireland and Northern Ireland. Dublin is the capital of the Republic and Belfast is the capital of Northern Ireland. Ireland is known for its beautiful scenery, stone walls without cement, ancient high crosses carved in stone, and small thatched cottages with whitewashed walls and central fireplaces. The Irish flag represents the two dominant religions in Ireland through its green, white and orange colors. Saint Patrick is celebrated on March 17th for bringing Christianity to Ireland and using the shamrock to explain the Holy Trinity.
