Located in the 7th district of Paris, the mansion of Brienne is an 18th century building listed as a Historical Monument. Its construction was launched in the first half of the eighteenth century by François Duret then president of the Grand Council. Soon in disgrace, the latter is forced to sell the site under construction to find a situation.
Hand over hands over the years, the mansion of Brienne is bought at the beginning of the nineteenth century by Lucien Bonaparte who changes the interiors. He sold it a few years later to his mother, Letizia, thus becoming the palace of Madame, mother of the Emperor.
A habitual residence of the Minister of War and the Minister of Defense since 1817, he witnessed great historical events such as the organization of the victory of the First World War by Clemenceau, or the direction of the Provisional Government of 1944 by Charles de Gaulle. His office has been kept as is since that time.
