Calumet Light stands at Calumet Harbor on the eastern shore of Lake Winnebago in Wisconsin, within Columbia Park about a mile west of Pipe. A three-story open-air steel skeletal tower at the harbor edge, it is topped by two flashing white strobe lights. Its plain, utilitarian form reflects its practical purpose: serving both as a navigational aid for traffic on Lake Winnebago and as an observation point over the harbor and nearby lakeshore. The structure is significant for combining these two functions in a simple tower adapted to its waterfront setting.
