Here are some more additions to The Best Sites For Learning About St. Patrick’s Day (and April Fool’s Day):
Woodlands Junior School in Great Britain has some short and and accessible info on St. Patricks’ Day.
The San Francisco Chronicle has photos of St. Patrick’s Day celebrations throughout Northern California.
The Boston Globe has images of Boston’s St. Patrick’s Day Parade.
MSNBC has a slideshow about Dublin, Ireland.
I think you might also like live Irish music all year long from LiveIreland in Dublin. You can choose from a traditional & folk version or the more contemporary music.
