The Eagle Harbor Lighthouse 

The copper mining industry began on the Keweenaw Peninsula in the 1840s. Lake Superior’s unreliable disposition meant that passing ships needed navigational assistance, and in 1851 the original lighthouse was built. The wooden tower which supported a fourth-order Fresnel lens illuminated by an oil lamp soon deteriorated, and in 1871 it was replaced by the present red brick structure. In 1895 a fog signal was added.

In the 1960s, the Fresnel lens was replaced by aviation beacon-type white and red lights, which beam their warning to ships more than 20 miles offshore. After being tended by 22 keepers since 1851, the lighthouse became automated in 1980 and the last personnel left in 1982.

Since 1982 the Keweenaw County Historical Society has maintained four museums at the light station. Besides the lighthouse, they include a Maritime Museum in the old fog signal building, a Keweenaw History Museum located in the old U. S. Coast Guard Station garage, and Commercial Fishing Museum located in one of the assistant keepers' buildings.

(Photo: The current Marine Rotating Beacons equipped with a 12 volt/75 watt lamp/bulb at the top of the tower lacks the romance of the Fresnel lens but is much more efficient.)

In 1999, Congress transferred ownership of the Eagle Harbor Light Station to the Keweenaw County Historical Society. The U.S. Coast Guard continues to operate the light at the top of the tower as an active navigational aid, and as such, the top of the tower is not open to visitors.
