A 250+-year tradition, New York’s Irish (and those who wish they were!) have strut their stuff in honor of the Archdiocese of New York’s Patron Saint since four years before the Declaration of Independence was signed. The parade proudly passes St. Patrick’s Cathedral at Fifth Ave. and 50th St. en route to the Irish Historical Society, with six hours of music, marchers, and mayhem. A strict rule forbids floats, so the 150,000+ members of the parade pass by on foot. Line up anywhere along Fifth Ave. for prime viewing; we’re partial to the edge of Central Park, from 59th St. north.
