Harry S Truman National Historic Site includes the Truman Home in Independence, Missouri, and the Truman Farm Home in Grandview, Missouri. Both units are within the Kansas City metropolitan area. Harry S Truman (1884-1972), 33rd President of the United States, lived in the Truman Home from 1919 until his death. The white Victorian style house at 219 North Delaware Street was built by the maternal grandfather of Bess Wallace Truman (1885-1982), and was known as the "Summer White House" during the Truman administration (1945-1953). The site also includes the two adjacent homes of Mrs. Truman's brothers, and, across Delaware Street, the home of the President's favorite aunt and cousins. Built in 1894 by Harry Truman's maternal grandmother, the Farm Home is the centerpiece of a 5.25 acre remnant of the family's former 600-acre farm. Mr. Truman worked the farm as a young man, from 1906-1917. It was here, said his mother, that Harry got his "common sense." Several outbuildings are also on the site.

Established as a unit of the National Park Service in 1990, the park commemorates the life, military career, and Presidency of Ulysses S. Grant, as well as his wife Julia Dent Grant. The site, also known as White Haven, consists of 9.65 acres holding five historic structures (main house, stone building, barn, chicken house, and ice house).
