Watertown Historical Society [WI]
The Watertown Historical Society seeks to preserve and share knowledge of Watertown, Wisconsin's history. The society operates the Octagon House, one of the largest single family pre-Civil War residences in Wisconsin. Completed in 1854 by John Richards—a lawyer, mill owner, and early Watertown settler—the house now contains period rooms for public display.
The society offers a variety of publications and Octagon House guided tours.
