Boston Light, Massachusetts
The Boston Light, which sits on a small island in the outer section of the famous Boston Harbor, became the first operational lighthouse in America when it was first illuminated in 1716. The current tower dates back to 1783.
While all lighthouses in the U.S. are now fully automated, the Boston Light still has a civilian keeper (whose duties mainly revolve around the tours that come to the island every day, rather than the upkeep of the beacon). Little Brewster Island, where the Boston Light is located, can be visited as part of a harbor cruise.
