George Rogers Clark National Historical Park, located in Vincennes, Indiana on the banks of the Wabash River at what is believed to be the site of Fort Sackville, is a United States National Historical Park. A classical memorial here was authorized under President Calvin Coolidge and dedicated by President Franklin D. Roosevelt in 1936. In 1966 Indiana transferred the site to the National Park Service. Adjacent to the memorial there is a visitor center where one can see interpretive programs and displays. The center is located on South 2nd Street in Vincennes.
