Cantigny Park, part of the Robert R. McCormick Foundation, is the 500-acre Wheaton estate of Robert R. McCormick. It is home to the McCormick House, First Division Museum, formal gardens, picnic grounds, walking trails and a Visitors Center with banquet and dining facilities.

The Robert R. McCormick Foundation is dedicated to fostering communities of educated, informed, and engaged citizens. Through philanthropic grant-making and Cantigny Park, the Foundation works to make life better in Chicagoland. The McCormick Foundation, among the nation's largest foundations with more than $1.5 billion in assets, was established in 1955 upon the death of Col. Robert R. McCormick, the longtime editor and publisher of the Chicago Tribune.
