Fort Halifax is a park and historic site in Winslow, Maine. It is also known as the Fort Halifax State Historic Site.
Designated as a National Historic Landmark in 1968, Fort Halifax is best known for being the home of the oldest blockhouse in the entire United States. It was built in 1754 by English settlers as a means of protection to the colonial settlements located along the Kennebec River. It also served as Major General John Winslow?s garrison in 1754, when he arrived at the site with 600 soldiers.
What remains in the old fort is the blockhouse. Although it was only reconstructed in 1987 after a massive flooding destroyed the structure, it still used the original logs, making its integrity intact still.
