This building may be described as a dome and a portico, built from 1670 to 1676, by Charles Erard, director of the Academy of France at Rome, and decorated by Charles de la Fosse. The cupola is graceful, and if it were as well decorated as the Allerheiligen church of the palace at München, or the Apollinarus-Kirche at Remagen on the Rhine, it would be an imposing edifice; as it is, it seems under a cloud, and is only used as a _succursale_ or _dépendance_ of the Madeleine. It belonged to the convent of Augustinian nuns, now turned into barracks, but still showing a few remains of the cloister. It is strange that no one in these days should desire to build a round church under a dome ablaze with mosaic decoration. It might have a sanctuary as at Aix-la-Chapelle for the Divine offices, with a pulpit in the dome, which would have the advantage of being placed so that all the congregation could see the preacher. I am thinking at this moment of the beautiful Russian church in Paris, which is gorgeous with colour and gilding. Such a building upon a large scale, built in the sumptuous style of the Brompton Oratory, of marbles and mosaic, and in the form of the church of the Assumption, would be a refreshing change from red brick and Doulton tiles, which seem to be inseparately mixed up with elaborate ritual, and are as infallibly correct as clothing for an Anglo-Catholic service as is chocolate colour for dressing up _pseudo_-Grecian temples surmounted by pepper-box turrets, which delighted the architects at the beginning of this styleless century. NOTRE-DAME DE L'ABBAYE AUX BOIS. If I say that the little church and cloister, which are all that remain of a monastery of Cistercian nuns, built in 1718, are situated in the Rue de Sèvres, hard by the Bon Marché, my readers will immediately picture their whereabouts. At the beginning of this century, the Abbaye became a genteel boarding-house for fashionable ladies who played at being weary of the world; but, although they retired into a monastic building, their _monde_ followed them; and thus we find Madame Recamier receiving her admirers in her cloistered _salon_, and listening to their philosophical sophistries while she elegantly reclines upon a satin sofa with straight legs and curling arms.
