Napoleon III's bedroom was decorated with a talisman from Charlemagne (a symbol of good luck for the Bonaparte family), while his office featured a portrait of Julius Caesar by Ingres and a large map of Paris that he used to show his ideas for the reconstruction of Paris to his prefect of the Seine department, Baron Georges-Eugène Haussmann. The Emperor's rooms were overheated and were filled with smoke, as he smoked cigarette after cigarette. The Empress occupied a suite of rooms just above his, highly decorated in the style of Louis XVI with a pink salon, a green salon and a blue salon.
