Grand Marais Light

Grand Marais Light is a twin beacon system in a harbor town on Lake Superior, featuring a front range light on a steel framework and a rear light with an octagonal lantern tower. The two structures work together to guide vessels entering the waterway.

The facility began operating in 1886 after Congress approved funds to improve navigation safety for vessels entering the harbor during maritime trade expansion. The system was installed to reduce accidents along this hazardous coastline.

The former keeper's house now serves as a local history museum, displaying maritime objects and records related to shipping on Lake Superior. This collection reflects how central waterborne trade was to the town's growth and identity.

Access to the grounds is via Broadway Street with parking available nearby. From there, you can walk along the breakwater to view both light structures.

The system uses two aligned lights to guide ships precisely into the harbor, which differs from traditional single-beam navigation methods. This design allowed captains to maintain their exact course toward the harbor opening.
