Rock of Ages Lighthouse is located just outside Washington Harbor 5 miles (8 km) off the northwest tip of Isle Royale National Park in Michigan’s Keweenaw County. Built in 1908, this lighthouse still serves as a navigational aid for boats. It is one of the tallest lighthouses on Lake Superior and is the tallest in the park standing at an impressive 130 feet (40 m) on a remote reef. Due to its size and isolated location, its construction was a major feat of engineering. It was listed on the National Register of Historic Places in 1983.
