We enjoyed this museum very much. The exhibits are all in one large room but there is a lot to see. We spent 1.5 hours there. They have a lot of artifacts such as lights and lenses; historical photos; and some large models of certain Maine lighthouses. They have good explanations posted with most items telling how they were used. Some of the descriptions told details about the duties and daily lives of the lighthouse keepers. There are restrooms by the entrance, and a nice gift shop as you exit. Admission was $10, less for seniors.
