Fort Mackinac is located on Mackinac Island between Lake Michigan and Lake Huron. It was built by the British during the Revolutionary War and not given up by them until fifteen years afterwards. From 1875-95 it was known as Mackinac National Park, the second national park after Yellowstone. The Fort was closed in 1895 and transferred to the State of Michigan, becoming its first state park. Fourteen buildings survive. The first photo is undated, and it shows the Fort situated 150 feet above the Straits of Mackinac.
