Blue Hill Bay Lighthouse

Blue Hill Bay Lighthouse — also known as Eggemoggin Light — was built in 1857 to guide mariners safely into Eggemoggin Reach and Blue Hill Bay, which was a busy lumbering port in the 19th century. Located on tiny Green Island, this lighthouse played a pivotal role in ensuring the safety of ships navigating the rocky and often unpredictable waters of the Maine coast, where the reach provided a vital route for vessels transporting timber and other goods.

The lighthouse itself is a classic example of 19th-century lighthouse architecture, featuring a tall, white cylindrical tower with a lantern room at its top. One unique aspect of Blue Hill Bay Lighthouse’s history is the way the keepers communicated with the mainland, a challenge due to the lighthouse’s remote location. According to historian Jeremy D’Entremont, in the 1920s when a keeper was needed on shore, a woman living across the water on the mainland would hang a black suit outside her house as a signal.

Today, Blue Hill Bay Lighthouse is privately owned and no longer serves as an active navigational aid, but it can be seen from boat tours in the area and from Naskeag Point Road in Brooklin.
