Fort Knox, one of the best-preserved 19th-century coastal defenses in the U.S., offers visitors an immersive experience in Maine’s military history. Built between 1844 and 1869, the granite fort features underground passageways, towering ramparts, and historic artillery placements. Adjacent to the fort, the Penobscot Narrows Observatory boasts the tallest public bridge observatory in the world. A high-speed elevator whisks visitors 420 feet above the river, where breathtaking panoramic views of the Penobscot Bay, distant mountains, and rolling forests await. This site is perfect for history buffs, photographers, and anyone looking for a unique perspective on Maine’s stunning landscapes.
