Close to the Rue du Marais, in the Rue de Sévigné, stands the Musée Carnavalet, established in the former Hôtel Carnavalet, where Mme. de Sévigné, author of the famous Letters, lived from 1677 to 1698. It was restored in 1867 by Baron Haussmann, who converted it into a museum for preserving various monuments, statues, inscriptions, tombstones, ornaments, and objects of various kinds, proceeding from the wholesale demolition to which sundry streets and even whole quarters of Paris were at that time being subjected, under the orders of Baron Haussmann himself in his capacity of Prefect of the Seine. Another remarkable mansion in the same street is the Hôtel Lamoignon, now occupied by different manufacturers, especially of chemical products, but which, in its earliest days, had highly aristocratic and even royal occupants. Begun by Diana of France, legitimatised daughter of Henri II., the Hôtel Lamoignon was bought and finished in 1581 for Charles de Valois, Duke of Angoulême, natural son of Charles IX., who, according to Tallemant des Réaux, would have been "the best fellow in the world if he could only have got rid of his swindling propensities." When his servants asked him for money, he would reply to them: "My house has three outlets into the street; take whichever of them you like best." The architecture of the Hôtel Lamoignon is that of an ancient fortress, though its walls and façades are ornamented with crescents, hunting horns, and the heads of stags and dogs; the whole in allusion to the Diana for whom the building was originally planned.
