Calumet is a census-designated place in Mount Pleasant Township, Westmoreland County, Pennsylvania, United States. Although the United States Census Bureau included it as a census-designated place with the nearby community of Norvelt for the 2000 census, they are in reality two very different communities, each reflecting a different chapter in how the Great Depression affected rural Pennsylvanians. As of the 2010 census, Calumet-Norvelt was divided into two separate CDPs officially. Calumet was a typical "patch town," another name for a coal town, built by a single company to house coal miners as cheaply as possible. The closing of the Calumet mine during the Great Depression caused enormous hardship in an era when unemployment compensation and welfare payments were nonexistent. On the other hand, Norvelt was created during the depression by the US federal government as a model community, intended to increase the standard of living of laid-off coal miners.

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.
