OCHS was established in 1960 as a 501(c)3 non-profit organization. OCHS currently owns and operates three historic properties: The Hazel Wirth Archives and Research Center in downtown Cedarburg, Stony Hill School in Waubeka and Ozaukee County Pioneer Village in Saukville.

In 1962, the Ozaukee County Board of Supervisors designated ten acres of Hawthorne Hills County Park for the Ozaukee County Historical Society to restore, furnish and preserve historic structures from around the area. The Ahner House was the first such structure that was dismantled and rebuilt on this site. Since the 1960s, numerous other buildings were added to the collection of what has grown to 24 historic structures in the outdoor living history museum that is now known as the Ozaukee County Pioneer Village.

Ozaukee County Pioneer Village is open May through October and is visited by thousands of people each year, including over 2,000 students who participate in educational school tours. Many folks come for a relaxing Saturday or Sunday afternoon or attend some of the event held at the village; WWII Reenactment, Heritage Day, Antique Tractor Show or Bluegrass at the Village Festival to name a few. Regardless of why they come, the numerous visitors of all ages step back in time and experience rural Ozaukee County during the late 1800s and early 1900s to gain a unique appreciation of pioneer life.

Its mission: “The Ozaukee County Historical Society seeks to preserve, advance and disseminate knowledge of the history and heritage of Ozaukee County through historic preservation, education and programming”
