Fort Phoenix

Fort Phoenix is an American Revolutionary War-era fort located at the entrance to the Fairhaven-New Bedford harbor, south of U.S. 6 in Fort Phoenix Park in Fairhaven. The fort was originally built in 1775 without a name. Just off the fort in Buzzards Bay was the first naval engagement of the American Revolution, the Battle off Fairhaven on 14 May 1775. -from Wikipedia
