Old World Wisconsin, the Midwest's largest outdoor living history museum, showcases the life of immigrants to the State of Wisconsin in the 19th and early 20th centuries. It is owned and operated by the Wisconsin Historical Society and occupies nearly 600 acres in the rolling hills of the Kettle Moraine area of Southeast Wisconsin near the small village of Eagle. It includes nine ethnic farms plus a village with a blacksmith, cobbler, general store, church, inn, shoe shop, and several residences. Interpreters dress in period clothing and go about their daily chores of farming, cooking, laundry, shoe making, blacksmithing, etc. The 40 some odd historic builldings on the site were moved to Old World from various locations in the early 1970s. The museum was opened to the public as the bicentennial project of the State of Wisconsin in 1976.

For many years Old World hosted a Civil War reenactment during Labor Day weekend. The last one was held in 2008.
