Polymath Park is a 125-acre (0.51 km2) resort 60 miles (97 km) southeast of Pittsburgh, Pennsylvania, United States, in the Laurel Highlands of Western Pennsylvania. The site, near the village of Acme in Westmoreland County, is surrounded by private forest in the Allegheny Mountains and features four architectural landmarks: Frank Lloyd Wright's (1867–1959) Donald C. Duncan House and R. W. Lindholm Residence, and two others by Peter Berndtson (1909–1972), who was one of the original Wright apprentices. The park is near Wright's Fallingwater (23 miles) and Kentuck Knob (29 miles). Duncan House and Lindholm House are the only Wright houses in the area that accommodate overnight visitors. Berndtson's 1962 master plan for Polymath Park allowed for 24 dwellings, each sited in a circular clearing in the forest. Only two houses, however, were actually built: the Balter House in 1964 and the 1965 Blum House. Duncan House was added to the park in June 2007. Built in 1957 in Lisle, Illinois, for Donald and Elizabeth Duncan, Wright's prefab Usonian was deconstructed in suburban Chicago in 2004 and reassembled in Pennsylvania. Lindholm House, named Mäntylä, was built in 1952 for R. W. Lindholm at Cloquet, Minnesota, and was dismantled in 2016 and rebuilt at Polymath Park in 2018. It opened in April 2019. Polymath Park is run by the nonprofit Usonian Preservation Corporation. Proceeds from rentals go toward maintenance of the houses and to architectural education programs.
