Duluth South Breakwater Outer Light
Duluth South Breakwater Outer Light, Lighthouse at Duluth Ship Canal, Minnesota
The brick structure stands 44 feet high with a rectangular fog signal building and two-story lantern superstructure on the south breakwater entrance.
The lighthouse began operations in 1874 to guide ships at the Northern Pacific Railroad docks, receiving a fifth-order Fresnel lens for navigation purposes.
The structure represents the maritime development of the Great Lakes region through its engineering design and transportation significance during industrial growth.
The fixed green light emits from the focal plane at a height of 44 feet above water level, remaining visible up to 17 miles offshore.
The lighthouse incorporated a specialized parabolic reflector filled with sawdust to redirect fog whistle noise away from residential areas in 1885.
