Located within Pictured Rocks National Lakeshore, this picturesque lighthouse stands on Au Sable Point on the south shore of Lake Superior, approximately 12 miles west of Grand Marais, Michigan.
Built in 1873-1874, the light tower's base diameter is 16 feet with a height of 87 feet. The lens focal plane is 107 feet above lake level. A brick oil building and fog signal building were built in the1890s. All of the buildings on site, along with the tower and keepers quarters, make up the light station.
The original one-story keepers dwelling was attached to the light tower in the back. In 1909, a new residence was built for the head keeper and another story was added onto the existing building so that it could accommodate two assistant keepers and their families. One family lived upstairs, one down. In 1945 the U.S. Coast Guard took over, replacing the civilian keepers.
