The new Penobscot Narrows Bridge, spanning the Penobscot River, welcomes visitors to Bucksport, a town founded in 1763 by Jonathan Buck. Bucksport was the site of the second-worst naval defeat in American history (the first was Pearl Harbor), in 1779, when a British Armada defeated the fledgling American Navy. It became known as "the disaster on the Penobscot." You can learn more about it at the museum in Bucksport or at the Penobscot Marine Museum in Searsport. Fort Knox, Maine’s largest historic fort, overlooks the town from across the river. There are magnificent views of the imposing granite structure from the pleasant riverfront walkway downtown.
