Nearer to Vendôme is the Château of Rochambeau. The present mansion that has replaced the ancient castle is a very insignificant and tasteless structure. All the interest it possesses consists in its dependencies that are rock-hewn. The bass-court is reached through a long and lofty gallery bored athwart the rock, and issuing from it we find ourselves in a sort of open well, probably originally natural but appropriated and adapted by man to his needs. This vast depression, the walls of which are seventy-five feet high, is circular, and measures eighty feet in diameter. Round it are cellars and chambers for domestic purposes. Others are accessible from the gallery that leads to the court. One of them, the Cave-Noire, possesses a chimney bored upwards through the rock to the level of the surface. Another peculiarity of this cavern is that along one side, throughout its length, 120 feet, are rings cut in the rock showing tokens of having been fretted by usage. They are at the height of four feet above the soil, and are on an average four feet ten inches apart. A second range is three feet or four feet higher up. In an adjoining cavern are similar ranges of rings. A third is cut almost at the level of the soil. Precisely the same arrangement is to be found at Varennes hard by in artificial caves still employed as stables, and some as dwellings for families. In the park is shown the cave in which the Duke of Beaufort, the Roi des Halles, was concealed when he escaped from the prison of Vincennes. François de Vendôme, Duke of Beaufort, was a grandson of Henri Quatre, a man of inordinate conceit and of very limited intelligence. During the regency that began in 1643, he obtained the confidence of Anne of Austria, but his vanity rendered him insupportable, and he went out of his way to insult the regent, so that she sent him to Vincennes. Voltaire passes a severe judgment on him. He says of the Duke: "He was the idol of the people, and the instrument employed by able men for stirring them up into revolt; he was the object of the raillery of the Court, and of the Fronde as well. He was always spoken of as the Roi des Halles, the Market-King." One day he asked the President Bellevue whether he did not think that he--Beaufort--would change the face of affairs if he boxed the ears of the Duke of Elbeuf. "I do not think such an act would change anything but the face of the Duke of Elbeuf," gravely replied the magistrate. There are in the Quartier S. Lubin at Vendôme chambers still occupied in the face of the cliff, high up and reached by structural galleries. At Lisle, on the river above Vendôme, are many caves, one of which was the hospital or Maladerie.
