Fort Allen (Portland, Maine)
Portland · Maine

History & Significance
Patriot forces established Fort Allen in 1775 as a simple earthen battery shortly after the Royal Navy's bombardment of Portland (then Falmouth) on October 18, 1775. The fort never saw combat during the Revolutionary War and was recorded merely as a "battery" on early maps.
When British forces captured coastal Maine cities in 1814 during the War of 1812, local militia urgently reconstructed the fort. Working at remarkable speed, 5,000 militiamen completed the rebuilt fortification in just 20 days, adding a magazine and barracks and positioning eight guns to defend Portland Harbor from its commanding height on Munjoy Hill.
The origin of the name remains debated: some sources attribute it to Revolutionary War hero Ethan Allen, while others credit Master Commandant William Henry Allen, a naval officer mortally wounded in the War of 1812, for whom the 1814 version was allegedly named. The fort was incorporated into a broader defensive network that included nearby Fort Sumner.
By the 1890s, the site's military purpose had ended. Mayor James P. Baxter and City Engineer William Goodwin transformed it into an urban park, completed in the 1890s and designed to showcase views of Casco Bay. The site holds National Register status and preserves visible earthwork remnants, a historic bandstand, and memorials honoring naval history spanning from the USS Maine to World War II vessels.
