Fort Defiance

Fort Defiance is a stone and earth fortification standing at Watch House Point that protected the inner harbor with eight artillery positions. The structure included an independent citadel and received upgrades in 1807 to accommodate seven artillery pieces.

The fort was built in 1794 under engineer Stephen Rochefontaine, replacing the British Fort Anne. It remained operational through several military conflicts until it diminished in importance during the American Civil War.

The site appears in an 1860 painting by artist Fitz Henry Lane, showing stone barriers topped with earth overlooking the harbor. The artwork captures how the fortification fit into the local maritime landscape of that era.

The site is located along the coast and is best accessed on foot as it sits within a harbor area. Visitors should come prepared for changeable coastal weather and wear sturdy shoes.

The fortification was initially known locally as Fort Lillie, while the U.S. Army simply called it Fort at Gloucester. The official name Fort Defiance was not established until 1814.
