Fort Halifax (Maine)

Fort Halifax is a former British colonial outpost on the banks of the Sebasticook River, just above its mouth at the Kennebec River, in Winslow, Maine. Originally built as a wooden palisaded star fort in 1754, during the French and Indian War, only a single blockhouse survives. A National Historic Landmark, it is the oldest blockhouse in the United States. It is now set in a municipal park, and is open to the public in the warmer months. It was the first of three significant forts which the British built on the major rivers in the Northeast to cut off the native water ways to the ocean (also see Fort Pownall and Fort Frederick (Saint John, New Brunswick)).^[4]
