Stora Karlsö Lighthouse (), is a Swedish lighthouse on Stora Karlsö island off Gotland in the Baltic Sea. It was built in 1887 and resulted in the first permanent settlement on the island in modern times. A house for the lighthouse keeper was built in the 1930s. In 1974, the lighthouse became fully automated when a cable for electricity was laid to the island and the last permanent residents left the island. Read more on Wikipedia
