Michigan: The Landlocked State With the Most Lighthouses

Michigan has the most lighthouses of any U.S. state—over 120—despite having no ocean coastline. This is because Michigan is bounded by four of the five Great Lakes (Superior, Michigan, Huron, Erie), which collectively form the largest freshwater system on Earth. These inland seas have hazardous shores, reefs, shoals, and heavy commercial and recreational traffic, necessitating extensive navigational aids. Michigan's lighthouses range from 1820s stone towers (Fort Gratiot) to iconic cast-iron structures (Big Sable Point, White Shoal) and modern skeletal towers. The state's "Lighthouse Trail" tourism route highlights this unique maritime heritage. Florida (~30) and Maine (~60) rank second and third, but their counts are for ocean coasts. Michigan's freshwater lighthouse network is unparalleled globally.
