- Halfway Rock Lighthouse
- Casco Bay, Maine - United States
Halfway Rock Lighthouse is a historic lighthouse located on a remote rocky island in Casco Bay, Maine, approximately 9 miles southeast of Portland. Its construction was prompted by the increasing maritime traffic in the area during the mid-19th century.
The construction of Halfway Rock Lighthouse began in 1853, and the lighthouse was first lit on January 1, 1872. The name "Halfway Rock" comes from its location, as it is situated roughly halfway between Portland Head Light and Cape Elizabeth Light.
The lighthouse was built to guide ships through the treacherous waters of Casco Bay, which were known for their numerous rocky outcroppings and dangerous shoals. Its purpose was to warn vessels of the hazardous conditions and to prevent shipwrecks.
The original lighthouse structure was a cast iron sparkplug-style tower standing 76 feet tall. It featured a fourth-order Fresnel lens that emitted a white light, which was visible for up to 16 nautical miles. The lighthouse was manned by a rotating crew of keepers who were responsible for maintaining the light and ensuring its reliability.
Over the years, Halfway Rock Lighthouse faced numerous challenges. The exposed location made it susceptible to severe storms and harsh weather conditions. In 1894, the original cast iron tower was replaced with a new cylindrical brick tower to withstand the elements better.
Automation came to Halfway Rock Lighthouse in 1975 when it was converted to an unmanned automated beacon. The keepers were no longer necessary, and the lighthouse was remotely operated.
Halfway Rock Lighthouse remains an important navigational aid in Casco Bay, although it no longer houses a physical presence of keepers. It stands as a testament to the maritime history of the area and serves as a symbol of the dedication and bravery of the keepers who once manned the lighthouse.
Today, Halfway Rock Lighthouse is still an active aid to navigation, maintained by the U.S. Coast Guard. While the lighthouse itself is not open to the public, visitors can see it from a distance by boat or during scenic cruises around Casco Bay. Its picturesque location and rich history make it a notable landmark in the region.
