Fort Knox, Maine's largest historic fort, features stunning military architecture and master granite craftsmanship. Constructed between 1844 and 1864 by master craftsmen and never fully completed, this is an unaltered example of a large mid-19th century granite coastal fortification. It is also New England's finest unmodified specimen of military architecture of the period.
