Fort Fairfield is a town in Aroostook County, settled in 1816 and incorporated on March 11, 1858, from Plantation D R1 and all of the Plymouth Grant lying southeast of the Aroostook River. It annexed Sarsfield Plantation in 1867. Fort Fairfield, established to protect the area during the Aroostook War, took its name from Maine Governor John Fairfield. The original fort (1839-1843), a duplicate of Fort Kent, was dismantled in 1862. A replica of the blockhouse was built in 1976 and is located in a small, quiet park just off Main Street. — Maine, An Encyclopedia
