Prospect Harbor Lighthouse is on the Naval Base in community of Prospect Harbor, Gouldsboro, Maine. Picture taken from a friend's house on the opposite shore. en.wikipedia.org/wiki/Prospect_Harbor_Point_Light It is a very sad day here after the loss of this historic and picturesque building. So far I have not heard of any deaths or injuries although I believe guests were staying in the cottage overnight when it happened. Shared in large part for it's historical significance.
