Officially Kilometer 1 of the Kiel Canal, the 13th-century town of Brunsbüttel has many fine half-timbered houses, but it is most famous for the massive locks constructed from 1907 to 1914. In addition to several lighthouses, the town’s 38-meter-tall (125-foot-tall) red-brick water tower, built in 1911, is a local landmark. In recent years, the town has also become famous for its popular Mud Olympics in July, when athletes compete in volleyball, football and other events in the estuary of the Elbe River.
