Swiss immigrants brought eighteen heifers and three calves to New Glarus, Wisconsin, in 1846. That was the beginning of what eventually grew into a rich cheese making heritage in Green County. Once home to 300 cheese factories, the number has dwindled to 12 today. However, Green County is still one of the nation’s leading cheese manufacturers. The National Historic Cheesemaking Center in Monroe, Wisconsin, shares Green County’s cheese making history with visitors.
