On the South Portland waterfront, survey the scene of the Battle of Portland Harbor, which is the only known Civil War conflict fought in Maine.

Visit Fort Preble to learn about a part of Portland’s 19th-century military history. Now part of the Southern Maine Community College campus, the fort is open for the public to explore. Pack a picnic or take a stroll along the water and enjoy the stunning views of Portland’s skyline.

Refresh your knowledge of American history here. Fort Preble was built in 1808 to enforce the Embargo Act, which President Thomas Jefferson had enacted the previous year. The act prohibited merchants from trading with the British and French to preserve neutrality during the Napoleonic Wars. The fort is named after Commodore Edward Preble, a decorated naval officer.

Stroll along the circular path around Fort Preble. Examine the stone buildings, complete with holes for cannons. In 1863, this was the scene of the Battle of Portland Harbor, the only known conflict fought in Maine during the Civil War. After Confederate sailors stole a civilian ship and entered Portland Harbor disguised as fishermen, the Union Navy raced after them and a battle ensued, ending in a Union victory.

Admire the beautiful views of Portland Harbor. Spot Fort Gorges, which was built on Hog Island Ledge to support Fort Preble. Note Fort Scammel, constructed on House Island to protect the harbor.

Watch a parade of boats sail through the harbor. Snap a photo of Portland’s picturesque skyline, dotted with stately wood-framed homes and oceanfront cottages.

Follow the large breakwater, which stretches between Fort Preble and Spring Point Ledge Lighthouse. Walk along the jetty to the small sparkplug lighthouse, which has been guiding ships through the harbor since it was built in 1897.

Explore Fort Preble throughout the year. During summer, it is a beautiful place to have a picnic. In winter, admire the landscape blanketed in snow. There is no entry fee to visit. Park in the small lot adjacent to the fort.
