The one-room, steel-and-glass house designed by Ludwig Mies van der Rohe that has been called one of the most important works of 20th century architecture. Located in a beautiful meadow on the banks of the Fox River two miles south of Plano, the Farnsworth House has been called “sculptural” in its simplicity and a masterpiece of design. Mies’ temple-like pavilion both invites and challenges visitors. Its unsurpassed views through transparent walls will cause you to consider anew how a man-made object best relates to nature. It’s not like any house you have ever been in. The Farnsworth House is owned by the National Trust for Historic Preservation and operated as a house museum by the Landmarks Preservation Council of Illinois. Transcending any traditional domestic function or program, the importance of the house lies rather in the absolute purity and consistency of its architectural idea.
