Halfway Rock Lighthouse

Halfway Rock Lighthouse, constructed in 1871, stands on a remote two-acre granite ledge in Casco Bay, approximately ten miles offshore from Portland, Maine. Its name reflects its position midway between Cape Elizabeth and Cape Small. The 76-foot conical tower, built from dovetailed granite blocks, was designed to withstand the harsh marine environment and originally housed a third-order Fresnel lens.

Due to its isolated and perilous location, Halfway Rock was designated a “stag lighthouse,” meaning it was considered too dangerous for keepers’ families. The lighthouse was manned continuously until its automation in 1975, after which it fell into disrepair.

In 2015, preservationist Ford Reiche purchased the deteriorating structure and undertook extensive restoration efforts. These included repairing the tower, reconstructing the dock, and restoring the keeper’s quarters. The project earned the highest award from the American Lighthouse Foundation in 2017.

Today, Halfway Rock Lighthouse remains an active aid to navigation. While not open to the public, it can be viewed from boat tours departing from Portland or Bailey Island. For more information, visit the Presumpscot Foundation’s website at halfwayrock.com.
