The bare, rocky islands of Utö are the main gateway to the Archipelago Sea. Since the 17th century, it has been a base for pilots, lighthouse keepers, custom officials and soldiers. The strange, rough beauty of these wind-beaten islets is an experience for the visitor. The sea, a paradise for pleasure boating in good weather, shows its terrifying power during autumn storms. Due to numerous shipwrecks, these waters have been aptly called the burial ground of ships. However, it is perhaps the colourful history of the island that the visitor finds most fascinating.
