Old World Wisconsin, the largest outdoor museum of rural life in the United States, is located near Eagle, Wisconsin, 35 miles (56 km) southwest of Milwaukee, in the Kettle Moraine State Forest. The open-air museum encompasses nearly 600 acres (2.4 km²) of rolling wooded hills and contains over 60 historic structures. These range from ethnic farmsteads with furnished houses and rural outbuildings to a crossroads village. In addition, a restaurant and conference space are located in the octagonal Clausing Barn, along with a gift shop. Trams run between the Scandinavian and German, African American, and Crossroads Villages.
