The only home Dwight and Mamie Eisenhower ever owned together sits on 189 acres adjacent to the Gettysburg battlefield, purchased in 1950 and used as a weekend retreat during Ike's presidency before becoming their retirement home in 1961. World leaders from Churchill to Khrushchev visited the farm, and the house is preserved as the Eisenhowers left it, with Mamie's famous "pink palace" décor intact.
