Split Rock Lighthouse is located in Minnesota on the west edge of Lake Superior. It was built in 1910 with all materials having to be brought in by boat. It was de-commissioned in 1969 and the site was donated to the Minnesota Historical Society, which restored it to its 1920 appearance. Split Rock Lighthouse is the most popular historical site in Minnesota, averaging 116,000 visitors annually. The first photo shows it nearing completion.
