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.
