Fort O’Brien State Historic Site
An active fort during the Revolutionary War, the War of 1812, and the Civil War, this site sits at the head of Machias Bay, where a naval battle was waged in 1775. Climb atop the grass-covered earthworks to take in the expansive water views. A panel display details the successive forts built here and relates the dramatic story of patriots—mostly armed with farm implements like pitchforks and axes—who captured a British tender in the bay. A stone marker honors the site as a "birthplace" of the U.S. Navy.
