The Indonesian Embassy started out as a 60-room mansion built by an Irish immigrant, Thomas Walsh, who struck gold in the Black Hills. His daughter, Evalyn Walsh McLean, lived it up as an heiress, snapping up the 45-carat Hope Diamond (she was its last private owner) as well as the 94-carat Star of the East. She was good friends with Alice Roosevelt Longworth, Theodore Roosevelt's daughter, who lived across the street.
