Constitution Ave. was a sea of green as Washington DC kicked off its annual St. Patrick’s Day Celebrations with a parade on Sunday March 11. Traditionally, the District hosts the parade on the Sunday preceding the actual St. Patrick’s Day which won’t arrive til March 17. The parade featured floats, Irish dancers, bands and military units. The grand marshall of this year’s parade was popular restaurateur Cathal Armstrong (Restaurant Eve, Virtue Feed and Grain). View our photos of the event by clicking on the photo icons below.
