Halfway Rock Light

Halfway Rock Light is a lighthouse standing on a rocky ledge in Casco Bay, roughly two miles from Portland. The conical granite tower features white exterior walls with a black lantern room at the top, rising about 23 meters high.

The lighthouse was built in 1871 by the U.S. Army Corps of Engineers following a series of shipwrecks in these perilous waters. Its construction marked an effort to improve navigation safety along the Maine coast.

The name comes from its location midway between two capes, serving as a crucial reference point for mariners navigating these waters. This landmark became deeply connected to the region's seafaring community and their understanding of safe passage through the bay.

The lighthouse can only be reached by boat since it sits on an isolated rocky ledge far from shore. Visitors should be aware that tides and weather conditions may affect boat access to the site.

The original conical tower and attached boathouse have survived intact, while storms have swept away every other building from the rocky foundation. This survival speaks to the resilient construction needed to withstand the harsh conditions of this exposed location.
