Sister cities of Superior, Wisconsin

Superior is a city in, and the county seat of, Douglas County in the US state of Wisconsin. The population was 27,244 at the 2010 census. Located at the junction of U.S. Highway 2 and U.S. Highway 53, it is immediately north of and adjacent to both the Village of Superior and the Town of Superior.

Superior is at the western end of Lake Superior in northwestern Wisconsin. Bordered by Saint Louis Bay, Superior Bay, and Allouez Bay, it is also framed by two rivers: the Nemadji and the Saint Louis. Superior, and the neighboring city across the bay, Duluth, Minnesota, form a single metropolitan area called the Twin Ports and share a harbor that is one of the most important ports on the Great Lakes. Both cities have museum ships (SS William A Irvin in Duluth and SS Meteor in Superior) devoted to the local nautical heritage. Superior was the last port of call for the Edmund Fitzgerald before its famous 1975 sinking.
