Those who have traveled and lived along the North Shore have been reliant on Lake Superior for food and – for many years – for transportation. In the late 1800s and early 1900s, lighthouses were built to mark treacherous reefs and to mark spots of refuge, like the Grand Marais Harbor. The lighthouse was built in 1884 and the Lightkeeper’s residence in 1896. Now home to the Cook County Historical Society, it is a museum with exhibits and archival storage.
