Isle Royale Light, Stone lighthouse on Menagerie Island, Isle Royale, US
Isle Royale Light is an octagonal stone tower with a black lantern and gallery positioned at the entrance of Siskiwit Bay on Lake Superior. The structure sits on Menagerie Island, a remote rocky outcrop, and stands about 19 meters tall.
Built in 1875, this lighthouse was established to guide ships navigating Lake Superior's waters. Its automation in 1913 reflected broader changes in maritime technology across the Great Lakes region.
The lighthouse represents the maritime heritage of the Great Lakes region and maintains its status on the National Register of Historic Places.
Reaching this lighthouse requires private boat transportation or a guided boat tour, as Menagerie Island is far from developed areas. Visitors should check conditions before traveling, since water access can vary with weather and seasons.
The lighthouse operates using a solar-powered 300mm optical system that projects light beams across considerable distances on the lake. This modern equipment demonstrates how remote light stations were updated with contemporary technology while preserving their original stone structures.
