Mansion Museum

The Mansion Museum is the home of the Winnebago Historical Society and also features the Leibrand-Whiteis Historical Center.  The Museum which was built at the turn of the century was built as the home of banker Charles J. Thompson. The Museum in addition to being a beautiful example of neoclassical architecture is also currently home to a variety of unique and rare collections and exhibits.
