"Irish Celtic Flag"
Although I have an Italian last name, 3 of my grandparents were Irish, so I enjoy celebrating my Celtic heritage on St. Patrick's Day.
Before I load up on Irish stew & Guinness, though, I wanted to post this excellent video I saw that explores the rich ancient heritage of Éire.
The documentary is from the Irish public broadcasting station, RTÉ. The video is an hour long, but worth watching if you're interested in Irish history.
