Gluges is on the Dordogne near Martel, where high up in the cliff, difficult of access, is the fortified cave-castle of Guillaume Taillefer, son of Raymond IV., Count of Toulouse, who was created Lord of Quercy in 972. Nearly on the level of the river is a cave half walled up, with traces of fresco on the walls, of course much later than the time of Taillefer. A modern house has been built on the platform that has been levelled, and much of the wall demolished; the upper fortified cave has an opening in the wall, pointed, of the thirteenth or fourteenth century. In much the same condition is another cliff castle in the rocks of the valley of the Alzou, between Grammat and Rocamadour, a little above the cascade of the mill Du Saut. I have elsewhere [Footnote: "A Book of the Cevennes," Lond., J. Long.] given an account of the curious castle of La Roche Lambert at Borne in Haute Loire, built in a basaltic cleft through which roars the river. It is the theatre of George Sand's novel, Jean de la Roche. "I may say without exaggeration that I was reared in a rock. The castle of my fathers is strangely incrusted into an excavation in a wall of basalt 500 feet high. The base of this wall, with that face to face with it, identically the same rock, forms a narrow and sinuous valley, through which winds and leaps an inoffensive torrent in impetuous cascades. The Château de la Roche is a nest of troglodytes, inasmuch as the whole flank of the rock we occupy is riddled with holes and irregular chambers which tradition points out as the residence of ancient savages, and which antiquaries do not hesitate to attribute to a prehistoric people. "The castle of my fathers is planted high up on a ledge of rock, but so that the conical roofs of the tower just reach above the level of the plain. My mother having poor health, and having no other place to walk save one tiny platform before the castle on the edge of the abyss, took it into her head to create for herself a garden at the summit of the crag on which we were perched midway."
