It's that time of year again when more than a million green-clad revelers fill the streets of America’s most Irish big city for the South Boston St. Patrick’s Day parade, celebrating the heritage and contributions of all those who hail from the Emerald Isle.
Sunday's parade dates back to the turn of the 20th century and marks both St. Patrick’s Day and Evacuation Day, which commemorates the day in 1776 when British troops left Boston after a protracted siege during the Revolutionary War.
