The State of Maine began construction of Fort Knox in 1844 in response to the Aroostook War and the threat of renewed conflict with Britain over the disputed Maine-New Brunswick border. The chosen site at Prospect, Maine, commanded the narrow point of the Penobscot River where British forces had advanced during the War of 1812 to seize Castine.
Fort Knox is the first fort in Maine built entirely of granite. Federal funding was intermittent across the construction period, and although approximately one million dollars was spent over 25 years, the fort was never fully completed to original specifications. Construction continued through 1869, by which point coastal defense doctrine had shifted in response to the lessons of the Civil War.
The fort was garrisoned only during the Civil War and Spanish-American War, and never saw combat. A workman was killed on September 26, 1844, when a powder keg ignited during construction. Sergeant Leopold Hegyi served as caretaker of the fort in the late nineteenth century and died on July 17, 1900, while in service at the site.
The Friends of Fort Knox operate the site in partnership with the State of Maine and have led ongoing preservation work. The adjacent Penobscot Narrows Observatory, the tallest public bridge observatory in the world, opened in 2007 and is included with fort admission.

Fort Knox's paranormal reputation has grown steadily since the late twentieth century, anchored by two documentable deaths at the site. A workman died on September 26, 1844, when a powder keg detonated during construction. Sergeant Leopold Hegyi served as caretaker through the late nineteenth century and died at the fort on July 17, 1900.
Reports from staff and visitors include phantom footsteps in the casemates, voices and laughter heard in empty rooms, and the sensation of being touched. A Travel Channel paranormal-locations series featured Fort Knox in a 2018 episode titled Cursed Towns. The Press Herald and other regional papers have covered the Friends of Fort Knox's October paranormal investigation fundraising events.
The fort's interior is well suited to atmospheric experiences: thick granite walls, dim natural light, and a maze-like layout of passages and rooms. Visitors should bring flashlights for the deeper interior spaces. Whether one credits the reports as paranormal or as the natural product of a vast, dim, unusual architectural environment, Fort Knox is one of the most rewarding self-guided historic-site visits in Maine.
