<p>The Duluth South Pier Breakwater Light is in need of some TLC these days.  The fresnel lens is encased in a plywood box.  The paint is peeling from the bricks of the chimney and the rest of the building.

This lighthouse is actually a combination of lighthouse and fog signal building.  It originally housed a large diaphone type foghorn.  Now it uses a tiny electric one.
