Built in 1725 for Mme de Prie, mistress of the Duke of Bourbon, then residence of the Princess of Conti and Laetizia Bonaparte, mother of the Emperor, all three have carried out major works that give the Hotel de Brienne prestige, elegance and, it is said, the most beautiful garden of the Republic. A key site in our military and political history, the Hôtel de Brienne has been the seat of the French Army Ministry since 1817. It is within these walls that Clemenceau organized the victory in 1917 and that Charles de Gaulle settled in 1944, once France was liberated. Their offices are renovated to the same level on the first floor while on the ground floor the offices of the minister and his advisers still bear the traces of our history and welcome those who write a new page.
