Fort Harrison, Florida Historic Marker courtesy of Fort Wiki
Fort Harrison, Florida, was a U.S. Army post established in April 1841 during the Second Seminole War by Major William Hoffman and troops of the 6th U.S. Infantry.
It was located on a bluff 25 feet above Clearwater Harbor, about 30 miles West of Fort Brooke. Two to seven companies of the 6th U.S. Infantry were stationed there during its occupancy under Lieutenant Colonel Gustavus Loomis. The post served as a U.S. Army recovery center for sick and wounded troops. In September 1841, five companies of troops were transferred back to Fort Brooke, and Fort Harrison was abandoned the next month.
Today, the site is on private property in Clearwater, Florida, in the Harbor Oaks development. A historical marker designates the site at 802 Druid Road South.
