St. Patrick´s Day.

Every year on March 17, the Irish and the Irish-at-heart across the globe observe St. Patrick’s Day. What began as a religious feast day for the patron saint of Ireland has become an international festival celebrating Irish culture with parades, dancing, special foods and a whole lot of green.
