There are several historic lighthouses on Lake Superior on or near the Apostle Islands in Wisconsin.

[2] Six of these lighthouses, all in the Apostle Islands National Lakeshore, were listed as a group on the National Register of Historic Places in 1977 under the name Apostle Islands Lighthouses.

The need for guidance increased in 1855 when the Soo Locks opened, connecting Lake Superior to the St. Lawrence Seaway to the east.

Shipping also increased as Duluth-Superior grew, and with the opening of Ashland's first ore dock in 1886.
