Fort Western is a former British colonial outpost at the head of navigation on the Kennebec River at modern Augusta, Maine, United States. It was built in 1754 during the French and Indian War, and is now a National Historic Landmark and local historic site owned by the city. It is the oldest surviving wooden fort in America, which still stands today. Its main building, the only original element of the fort to survive, was restored in 1920 by William H Gannett and Guy P Gannett and now depicts its original use as a trading post. The Gannett's then gifted the building back to the City of Augusta, and it opened as a museum on July 4th, 1922.
