The Harry S. Truman Little White House is an unusual historic site in that it was the winter White House of America from 1946 to 1952 and continued to be used by later Presidents. Here presidents relaxed and restored body and mind while dealing with the threats of the Cold War.

Visitors to Key West can tour the Little White House in Truman Annex. Knowledgeable tours guides introduce visitors to the 'personal' of the Harry S. Truman Presidency, as well as offering a glimpse into the politics of the Cold War and the Naval History of Key West.
