Since 1890, history has left its mark on the Truman Little White House. Initially, it served as the naval station’s command headquarters during the Spanish-American War, World War I and World War II. In 1946 the historic building first served as the winter White House of President Harry S. Truman and a site for the Cold War response by later presidents. Today, the Truman Little White House is a public, living, Key West museum as well as a retreat and place of government business by our nation’s leaders.
