Ivanhoe: A Romance by Sir Walter Scott

Note to Chapter XLI

Note J.—Castle of Coningsburgh.

When I last saw this interesting ruin of ancient days, one of the very few remaining examples of Saxon fortification, I was strongly impressed with the desire of tracing out a sort of theory on the subject, which, from some recent acquaintance with the architecture of the ancient Scandinavians, seemed to me peculiarly interesting. I was, however, obliged by circumstances to proceed on my journey, without leisure to take more than a transient view of Coningsburgh. Yet the idea dwells so strongly in my mind, that I feel considerably tempted to write a page or two in detailing at least the outline of my hypothesis, leaving better antiquaries to correct or refute conclusions which are perhaps too hastily drawn.

Those who have visited the Zetland Islands, are familiar with the description of castles called by the inhabitants Burghs; and by the Highlanders—for they are also to be found both in the Western Isles and on the mainland—Duns. Pennant has engraved a view of the famous Dun-Dornadilla in Glenelg; and there are many others, all of them built after a peculiar mode of architecture, which argues a people in the most primitive state of society. The most perfect specimen is that upon the island of Mousa, near to the mainland of Zetland, which is probably in the same state as when inhabited.

It is a single round tower, the wall curving in slightly, and then turning outward again in the form of a dice-box, so that the defenders on the top might the better protect the base. It is formed of rough stones, selected with care, and laid in courses or circles, with much compactness, but without cement of any kind. The tower has never, to appearance, had roofing of any sort; a fire was made in the centre of the space which it encloses, and originally the building was probably little more than a wall drawn as a sort of screen around the great council fire of the tribe. But, although the means or ingenuity of the builders did not extend so far as to provide a roof, they supplied the want by constructing apartments in the interior of the walls of the tower itself. The circumvallation formed a double enclosure, the inner side of which was, in fact, two feet or three feet distant from the other, and connected by a concentric range of long flat stones, thus forming a series of concentric rings or stories of various heights, rising to the top of the tower. Each of these stories or galleries has four windows, facing directly to the points of the compass, and rising of course regularly above each other. These four perpendicular ranges of windows admitted air, and, the fire being kindled, heat, or smoke at least, to each of the galleries. The access from gallery to gallery is equally primitive. A path, on the principle of an inclined plane, turns round and round the building like a screw, and gives access to the different stories, intersecting each of them in its turn, and thus gradually rising to the top of the wall of the tower. On the outside there are no windows; and I may add, that an enclosure of a square, or sometimes a round form, gave the inhabitants of the Burgh an opportunity to secure any sheep or cattle which they might possess.

Such is the general architecture of that very early period when the Northmen swept the seas, and brought to their rude houses, such as I have described them, the plunder of polished nations. In Zetland there are several scores of these Burghs, occupying in every case, capes, headlands, islets, and similar places of advantage singularly well chosen. I remember the remains of one upon an island in a small lake near Lerwick, which at high tide communicates with the sea, the access to which is very ingenious, by means of a causeway or dike, about three or four inches under the surface of the water. This causeway makes a sharp angle in its approach to the Burgh. The inhabitants, doubtless, were well acquainted with this, but strangers, who might approach in a hostile manner, and were ignorant of the curve of the causeway, would probably plunge into the lake, which is six or seven feet in depth at the least. This must have been the device of some Vauban or Cohorn of those early times.
