This light, which marks the entrance to Machias Bay, was one of the best-built lighthouses in the Maine system. It has stood in its present condition for more than 180 years. Philmore Wass, who was raised here when his father was the keeper, wrote a memoir of that time, Lighthouse in My Life. The light is not open to the public and the keeper's house and other outbuildings no longer exist, but charter boat rides and cruises that offer water views of the tower are available.
Libby Island Light Station was built in 1822.
