Minnesota Point Light in Duluth stood at the edge of Lake Superior on a site long important to navigation, including Henry W. Bayfield’s 1823 survey of the lake. Built in 1858 as Minnesota’s first lighthouse and the first high-powered light on Lake Superior, it marked the entrance to the natural harbor formed by the sand bar and river outlet. The red-brick tower and keeper’s dwelling served only briefly as harbor access shifted with new piers and a ship channel in the late 19th century. Permanently closed in 1885, the station declined until only the weathered tower remained, later recognized for its transportation history.
