Dewey's home was designated as a historic site in 1954 and is listed on the National Register of Historic Places. It was deemed a place that would celebrate Wisconsin's rich agricultural heritage. By 1961, the more than 30 buildings that make up Stonefield Village were constructed and opened, offering visitors a historic perspective of farm life in rural Wisconsin.

The site's assortment of antique farm implements and machinery rapidly grew. This spurred construction of a new home for Stonefield's agricultural collections. In 1971 a new building raised on the foundations of Dewey's original sheep barn opened as the State Agricultural Museum. Today it houses Wisconsin's largest collection of farm tools, models, and machinery detailing the state's agricultural past.

Stonefield continues to enlighten us about the turn-of-the-century technology, the agricultural community that cultivated Wisconsin's growth and the colorful characters that helped make the state become "America's Dairyland."a
