As the Society Resource Center, it houses the organization’s collections, offices and research area. It’s original tin ceiling, wood floors and plaster walls were revealed through the restoration of the building. The building was awarded a Historic Preservation Excellence Award in 2014 by the Wisconsin Association of Historic Preservation Commissions.
