Built between 1905-1908 to resemble a 17th-century country estate, Duluth's 39-room "American Castle" retains the majority of its original furnishings and art and, amazingly, closely resembles the way it looked when its owners, the Congdon family, first occupied it in 1908. Situated on a wooded lot, the mansion boasts spectacular views of Lake Superior.

The Waters of Superior is a gallery and gift store featuring regional artists and items influenced by Lake Superior. The Bluelake Gallery, is housed in a 1873 building and features local and regional artists. Pottery, jewelry, metal sculptures, outdoor sculpture garden, and more, are there for viewing.
