Fort Baldwin

Fort Baldwin is a coastal defense installation on Sabino Hill in Phippsburg with three concrete artillery batteries. The structures command views of the Kennebec River and where it meets the Atlantic Ocean.

The fort was built between 1905 and 1912 by the United States Army Corps of Engineers to strengthen coastal defense near Bath Iron Works. Additional structures and equipment were added during World War II.

The fort displays military architecture from the early 1900s through its concrete structures and gun positions. Visitors can see how defense installations of that era were built and arranged.

The site is accessible via Sabino Head Road from the parking area or through the Perkins Farm Trail from a different trailhead. The walking paths are open and allow visitors to explore the batteries and grounds at their own pace.

The fort features four circular concrete mounts built to support mobile 155-millimeter artillery pieces installed during World War II. These gun platforms show how military engineering of the 1940s adapted to new mobile weapons technology.
