Lighthouses of the Great Lakes

The lighthouses of the Great Lakes are guiding structures built along the shores and navigational routes to aid ships in safely navigating the often treacherous waters. They emit powerful light signals, sometimes combined with sound signals, to warn of dangerous coastlines, reefs, and shallow areas, especially at night or during fog. Historically crucial for commerce and transportation, these lighthouses also serve as landmarks and symbols of maritime heritage. Today, many are preserved as historical sites or continue functioning as aids to navigation, helping ensure safe passage for vessels across the expansive and sometimes challenging Great Lakes region.
