Fort George | Castine

Fort George is a historic coastal fortification located in Castine, Maine, overlooking the Penobscot River and Blue Hill Bay. Built during the late 18th century, it played a strategic role in colonial and early American military history, serving as a defensive site during multiple conflicts between European powers and later during the American Revolution. Today, the site preserves the remnants of earthen walls and stonework, offering visitors a tangible link to the region’s turbulent past.

History and Significance
Fort George was originally constructed by the British in 1779 during the Revolutionary War as part of their effort to maintain control over the Penobscot River and the surrounding territory. The fort was part of a broader network of coastal defenses in Maine, reflecting the strategic importance of Castine’s peninsula, which commands access to the river and nearby maritime routes. Although it saw limited combat, Fort George was involved in the Penobscot Expedition, a failed American attempt to reclaim the area from British control, which remains one of the largest naval defeats in U.S. history prior to Pearl Harbor.

Architecture and Layout
The fort’s original structure included earthen ramparts, stone walls, gun emplacements, and barracks. Today, visitors can explore the remains of these fortifications, including partial walls and earthworks that outline the defensive layout. Interpretive signs help explain the fort’s original design and military function, while providing context about life for soldiers stationed there. The elevated position of the fort offers clear views of the surrounding harbor, making it easier to understand why the site was strategically chosen.
