The river Dunière sweeps past Vernoux, and the road from S. Fortunat to this town presents a succession of striking scenes. The gorge through which the Dunière enters the Erieux has precipitous sides, above which the mountains rise bare, or but meagrely dotted with evergreen oaks, that grow low and stunted. Below rolls, leaps, and foams the torrent. In the contracted throat of Pontpierre, after the bursting of storms in the Cévennes, the water rises and writhes to escape, and issues from it into the valley of the Erieux as from a spout. The road follows the edge of the chasm as far as Roumézoux, after which the hills fall back and allow of cultivation. Then again they contract, but the gorge is less savage, and is commanded on the left bank by one of the noblest ruins in the Vivarais. The Dunière flowing from the east receives a torrent descending from the north, and at this point rises a mighty crag on the top of which two lofty towers stand out sharply against the sky. They belong to the castle of La Tourette, close to Vernoux. According to popular tradition it was built by the Saracens; it was the feudal centre of the district and occupied by a Marquess de La Tourette. The castle was intact till the Revolution, and was a scene of much hospitality extended to the bourgeoisie of Vernoux, who danced in the great hall, hung with stamped and gilded leather. At the Revolution the castle was unroofed and ruin set in rapidly, as every one who wanted to build a pigsty or a factory used its walls as a quarry. Happily of late years the family of La Tourette, that has its residence at Tournon, has repurchased the eagle nest of its ancestors and has put a stop to the destruction. From its isolated rock the castle was connected by a drawbridge with a terrace, beyond which was the farm, a building of the sixteenth century, that had not been molested. The terrace is sustained by a wall and was originally planted with trees, and must have been a delightful walk, suspended above the precipice, and from which one could look down on the birds of prey darting and fluttering in the depths, and which also had their habitations in these rocks. In 1671, the Marquess de La Tourette bought the barony of Chalençon to the south of Vernoux. This was at one time one of the most powerful baronies in the country. It extended its jurisdiction over eighty parishes, all of which were bound to furnish men-at-arms when summoned to do so by the Seigneur of Chalençon.
