This is what www.historic-savannah.com has to say about this monument:
Once known as the Strand and later as Irish Green because of its proximity to the Irish residents of Savannah's Old Fort neighborhood, this park was renamed in 1902 for the Irish patriot Robert Emmet (1778-1803) to commemorate the centennial of his death. Emmet, who led an unsuccessful Dublin uprising for Irish independence and was executed for treason, was a hero to Savannah's Irish community. Emmet is best known for the speech in which he asked that his epitaph not be written until "my country takes her place among the nations of the earth.” Emmet Park remains an important center of ceremonial congregation for Savannahians of Irish descent.
Erected by the Georgia Historical Society and the St. Patrick's Day Parade Committee.

There was a lot more Irish going on in Savannah than I expected. Their St Patrick's Day Committee has a permanent brick-and-mortar office with a really cool sign.
