At the end of the terrace built for the princess Elizabeth, of England, is one of the round towers, which was split in twain by the French. Half has fallen entirely away, and the other semicircular shell which joins the terrace and part of the Castle buildings, clings firmly together, although part of its foundation is gone, so that its outer ends actually hang in the air. Some idea of the strength of the castle may be obtained when I state that the walls of this tower are twenty-two feet thick, and that a staircase has been made through them to the top, where one can sit under the lindens growing upon it, or look down from the end on the city below with the pleasant consciousness that the great mass upon which he stands is only prevented from crashing down with him by the solidity of its masonry. On one side, joining the garden, the statue of the Archduke Louis, in his breastplate and flowing beard, looks out from among the ivy.
There is little to be seen about the Castle except the walls themselves. The guide conducted us through passages, in which were heaped many of the enormous cannon balls which it had received in sieges, to some chambers in the foundation. This was the oldest part of the Castle, built in the thirteenth century. We also visited the chapel, which is in a tolerable state of preservation. A kind of narrow bridge crosses it, over which we walked, looking down on the empty pulpit and deserted shrines. We then went into the cellar to see the celebrated Tun. In a large vault are kept several enormous hogsheads, one of which is three hundred years old, but they are nothing in comparison with the tun, which itself fills a whole vault. It is as high as a common two story house; on the top is a platform upon which the people used to dance after it was filled, to which one ascends by two flights of steps. I forgot exactly how many casks it holds, but I believe eight hundred. It has been empty for fifty years.
