The new Opera House, which was to replace the one burnt down in 1873, had already, on a scale of unprecedented magnificence, been designed, constructed, and all but finished under Napoleon III. But 1873, scarcely more than two years after the disasters of the siege and Commune, was not the time at which to complete and inaugurate a sumptuous Opera House; and it was not until 1875 that the famous edifice, which may challenge comparison with any other of the kind in Europe, threw its doors open to the public. Another celebrated building in this neighbourhood, at the corner of the Rue Taitbout, is the former Hôtel de Brancas, built by the architect Bélanger, a devoted friend of the famous Sophie Arnould, to whom he was faithfully attached until her death. His endeavours to obtain for her, in default of a pension that was never paid, a portion of the large sum due to her from the directors of the Théâtre Français show him to have been a man of energy as well as heart. It was in the character of architect that Bélanger first became acquainted with the brilliant and witty actress; and when he made her an offer of marriage, which she did not accept, she at once observed that no one was better fitted than an architect to build up her damaged reputation. From the family of Brancas the mansion erected by Bélanger passed to the wife of General Rapp, then to the Marchioness of Hertford, to her son Lord Seymour, and to Sir Richard Wallace. Under Napoleon III. magnificent entertainments were given there by the late Khalil Pasha. On the ground-floor of the edifice appeared and disappeared the Café de Paris, celebrated in the reign of Louis Philippe, and for some years afterwards, as the rendez-vous of celebrities in literature, art, and the world of fashion. It was in time to be followed by other excellent restaurants, now vanished, but not forgotten. The last house on the Boulevard des Italiens, at the corner of the Rue de la Chaussée d'Antin, occupies the site of the old Military School, founded, for 200 officers' sons, under the name of Dépôt des Gardes Français; where for twenty years of his life Rossini lived on the first floor, and whence he moved to the villa at Passy offered to him by the City of Paris. It was in this retreat that he ended his days. [Illustration: RUE DE LA CHAUSSÉE D'ANTIN.]
