Fort Knox State Historic Site (Maine)
Prospect, ME
Fort Knox in Prospect, Maine, is the first fort in the state built entirely of granite. Construction began in 1844 and continued intermittently through 1869, intended to protect the Penobscot River Valley against possible British incursion following the Aroostook War. The fort never saw combat. Sergeant Leopold Hegyi served as caretaker until his death on July 17, 1900.
