Lake Superior Marine Museum Association Acquires Duluth Harbor’s South Breakwater Outer Light

By GLSR Staff  |  Latest News, Lighthouses, Ports & Terminals
The Lake Superior Marine Museum Association (LSMMA) has acquired the Duluth Harbor South Breakwater Outer Light in an effort to preserve an instrumental piece of maritime heritage. The historic lighthouse, a one-and-a-half story brick building with a distinctive white facade and red roof, has served as a beacon at the entrance to the Port of Duluth-Superior since 1901. 

“We’re excited to acquire this iconic facility, refurbish it, and share it with the community,” said LSMMA Board Member Al Finlayson. “Preserving maritime artifacts—and in this case, one that’s still in use—is core to our LSMMA mission. We’re grateful for the support we’ve received to embark on this challenging but beneficial effort. Discussions are already underway with local experts who will help perform the repairs, and very soon, we’ll begin a fundraiser to help save this facility for present and future generations.” 

A Century of Service 

The South Pier Light Station welcomes approximately 700 vessels each year into the port. Originally constructed at the turn of the 20th century, the South Pier Light Station replaced earlier wooden lighthouse structures that served the port since the 1870s. The current brick structure was first illuminated on Sept. 1, 1901, and was designed to work in tandem with the Inner Breakwater Light to create a range system guiding ships safely through the canal.  

Restoration Plans 

LSMMA plans to restore the lighthouse to its early 1900s condition and make it available for public tours within the next couple of years. The structure, which was added to the National Register of Historic Places in 2016, has deteriorated from pigeon infestation, vandalism and natural wear over the decades, but remains structurally sound.  

The U.S. Coast Guard continues to operate the active navigation light and foghorn within the building, ensuring the lighthouse maintains its vital role in harbor safety. Its fixed green beacon is visible up to 17 miles away. Crafted in Paris, France, the original fourth-order Fresnel lens from the station is currently displayed at the Lake Superior Maritime Visitor Center in Canal Park.
