Join a special Open House at the Copper Culture Museum within Copper Culture State Park in Oconto, WI, on Saturday, June 28, 2025, from 10:00 AM to 4:00 PM. Celebrate the newly refreshed building and captivating exhibits that delve into the lives of ancient people in northeast Wisconsin thousands of years ago. As a highlight of the Wisconsin State Parks system's 125th Anniversary, this free event welcomes everyone to explore the museum and park.

Discover the latest archaeological findings on the Old Copper Complex, including groundbreaking evidence suggesting these ancient people were among the earliest metallurgists in the world. The Oconto Site is uniquely significant as the only one in the Upper Great Lakes region with a museum dedicated to telling this remarkable prehistoric story. Learn about the direct ancestral ties to the Menominee Indian Tribe of Wisconsin.

The Open House will feature a refreshments tent and an Ancient Native American Artifacts Identification table in the front garden, where area collectors are invited to bring items for review. The museum, housed in a charming, intricately bricked farmhouse built over 100 years ago in Old World Belgian style, now boasts beautifully preserved maple floors and a thoughtfully enhanced double-sided fireplace featuring hand-painted panels by local artist Bruce Retzlaff. Operated by the Oconto County Historical Society, the Copper Culture Museum is open daily from Memorial Day to Labor Day, 10 AM to 4 PM, and by appointment during spring and fall.
