The Edith Farnsworth House, formerly the Farnsworth House,[6] is a historical house designed and constructed by Ludwig Mies van der Rohe between 1945 and 1951. The house was constructed as a one-room weekend retreat in a rural setting in Plano, Illinois, about 60 miles (96 km) southwest of Chicago's downtown. The steel and glass house was commissioned by Edith Farnsworth.

Mies created a 1,500-square-foot (140 m2) structure that is widely recognized as an exemplar of International Style of architecture. The retreat was designated a National Historic Landmark in 2006, after being listed on the National Register of Historic Places in 2004.[5] The house is owned and operated as a house museum by the National Trust for Historic Preservation.

In celebration of the 2018 Illinois Bicentennial, the Farnsworth House was selected as one of the Illinois 200 great places[7] by the American Institute of Architects Illinois component (AIA Illinois) and was recognized by USA Today Travel magazine, as one of AIA Illinois' selections for Illinois "25 Must See Buildings".[8]
