At last it came to the Counts von Firmian, who, in 1480, built a more convenient mansion at the foot of the cliff, and turned the old castle into a hermitage. The castle, that is in a fair condition, occupies a broad cleft in the rock, only accessible by a narrow path cut in the rocks on the west side. It consists of an outer court and an inner court, protected on the side of the precipice by a stout wall, behind which were originally chambers, as windows in the wall and beamholes show to have been the case. There is a donjon that reaches to the overhanging rock and a ruinous chapel with apsidal east end. The cleft runs further east, but is blocked with a wall. Another cliff castle, of which Merian, in his Topographia, 1640-88, gave a picture to arouse interest and wonder, is that of Covolo, at one time in Tirol, now over the Italian border. His description of it is as little accurate as his illustration. As a matter of fact, although it is certainly a cliff castle, constructed in a cave, it is accessible on foot, and it is by no means necessary to be conveyed to it by a windlass. Indeed it would not be easy to erect a crane on the platform of the castle that could haul up men and provisions from below. A more famous fortress in a cave is that of Schallaun in the Puxerloch. Here is a grotto in the face of the precipice, 75 feet above the valley. The cliff itself is 4500 feet high. The castle consists of two stages, the outer court is at a lower level than the face of the cliff, and the opening of the grotto. Entrance was obtained through this outer court that was reached by a path cut in the rock, and from it by a stair also rock-hewn. A second court was reached, above this was again a third within the cave. On the right hand the cave branches out into a long inner cleft that was closed at one time by a door, and was probably used as a cellar. The main cavern also runs by a narrow passage deep into the heart of the rock to a pool of crystal clear water, never failing. The main building--hardly a donjon, was occupied till late in last century by an old mason who patched it up and made it habitable. At a little distance to the east is a smaller cave also with a wall in front of it, and this is said by the peasants to have been the kitchen of the castle, and to have been reached by a wooden gallery from the main building. According to tradition, Schallaun derives its name from Chalons. In the time of Charlemagne a knight of Chalons named Charlot eloped with a Saxon princess, and took refuge in this cave. It became a den of thieves, and Margaret Maultasch (Pouchmouth) took and dismantled it. According to another story the castle served as the haunt of a shadowless man. Unlike Camizzo's hero, he had not sold his shade to the devil, but by a lapse of nature had been born without one. This proved to him so distressing, and so completely interfered with his matrimonial prospects that he took refuge in the Puxerloch, where
