The Ministry of War occupies a sort of island comprised between the Rue St.-Dominic, the Rue de Solferino, and the Rue de Bourgogne, with its principal entrance on the Boulevard St.-Germain, No. 231. The Dowager Princess of Conti inhabited the mansion until 1775, the year of her death. The next occupant was the Duc de Richelieu, who was succeeded by Loménic de Brienne, Archbishop of Toulouse, and at the same time Minister of War in the year 1786, and by his brother, the Comte de Brienne, in 1789. Without being designated “Ministry of War,” the house seemed destined to be occupied by a succession of War Ministers. At last, however, it became national property, and from 1802 to 1804 it was inhabited by Lucien Bonaparte. After the proclamation of the Empire, Napoleon gave it to Mme. Laetitia Bonaparte; and it was not until the Restoration that the Hôtel de Brienne became finally the official residence of the Minister of War. [Illustration: PALACE OF THE LEGION OF HONOUR.] Close by, on the Boulevard St.-Germain, formerly Rue St.-Dominic, is installed the Central Depôt of Artillery. It occupies the whole of the ancient cloister of the monastery of the Reformed Dominicans, whose church is dedicated to St. Thomas Aquinas. To the right of the church portal, the little Rue St.-Thomas Aquinas conducts the visitor to a space surrounded by symmetrical buildings. He is now in the heart of the ancient convent. The large door to the right is that of the historical cloister, where the Museum of Artillery found a home until it was transferred to the Hotel des Invalides. The religious establishment, of which nothing but the church survives, was the convent of the general noviciate of the reformed Dominicans or Jacobins, founded by Cardinal Richelieu in 1631. The construction of the church did not commence till 1638. The architect was Pierre Bullet, and the foundation stone was laid by the Duchess de Luynes. It was not until nearly the middle of the next century--1740--that the edifice was completed. The interior is richly adorned with paintings from the brush of Blondel, Picot, Guillemot, Lemoyne, Lagrenée, Michel Vanloo, and Ary Scheffer. The church of St.-Thomas Aquinas is the most aristocratic in Paris, and a wedding within its walls possesses enormous fascination for the curious sightseer. The Rue de Grenelle, which runs parallel to the old Rue St.-Dominique, is remarkable for a sculptural masterpiece--the fountain designed by Edmé Bouchardon, who himself executed the whole of the figures and bas-reliefs. The central figure, representing the town of Paris, and the two figures to right and left of it, symbolising the Seine and the Marne, are exquisite. Between the columns and beneath the pediment is a long Latin inscription, addressed by the Provost of the merchants of Paris to the glory of Louis XV., “the father and delight of his people, who, without shedding blood, has extended the frontiers of France.”
