 Preservationists and contributors from around the world, including the Friends of the Farnsworth House, began a concerted preservation and fund-raising effort to keep the house on its original site.With this financial support, the National Trust for Historic Preservation and Landmarks Illinois were able to purchase the house in December 2003 for a reported $7.5 million.Now operated as a house museum, the Farnsworth House is open to the public, with tours conducted by the National Trust.
