The City of Neillville is located in Clark County Wisconsin. It was first permanently settled in 1844 by the O’Neill brothers and other lumberman. By 1853 Clark County was organized and the Post Office was named “Clark”. Its name was quickly changed to “Neillsville” - named after our Founder James O’Neill Sr. And in a colorful set of circumstances, Neillsville was selected as the new County Seat. Neillsville continued as a Village until 1882 when it was chartered as a City. An early history of Neillsville WI (published in 1918) can be found here. The History of Neillsville and Clark County are important reminders of where we started, what life was like in this new territory, what has been accomplisihed over the years, and the legacy these settlers and founders have left to us - and that we must continue to care for. The City of Neillsville and its Historic Preservation Commission invite you to learn more about the many people who lived their lives here in Neillsville, the beautiful historic homes and businesses they built, and the community they called “home”.
